From COCOM to the Wassenaar Arrangement. A Beginner's History of Export Control Regimes

Hello, this is Ryuta Hamamoto from TIMEWELL.

Open almost any introduction to export control and, early on, you meet two names, the Wassenaar Arrangement and COCOM. Both are international frameworks. What is rarely explained is what they share, how they differ, and how either one connects to the Japanese rules on your desk today. Many people memorize the names and get confused later.

Here is the short answer. COCOM was a Cold War arrangement in which Western countries, aiming mainly at the communist bloc, required unanimous agreement before exceptions could be made. It ended on March 31, 1994, and the Wassenaar Arrangement, which started operating in 1996, took over. Wassenaar does not name a target country, and it leaves the final decision on each export to the participating state. In exchange, it maintains shared control lists and asks states to tell each other about denials. Japan's Export Trade Control Order, in its Appended Table 1, is built from those lists and from the agreements of three sister regimes covering nuclear, chemical and biological weapons, and missiles. Japan carries those agreements into law through ministerial amendments every year.

This article walks through how COCOM worked and how it ended, how Wassenaar is designed, how the four regimes divide the work, how they map to the items of Appended Table 1, and how Japan turns agreements into regulation. It also covers why people say the regimes struggle to reach agreement and what countries do in response. At the end, I connect all of this to your own classification work in practical terms.

The short version, and the words to know first

Before the history, here is a table of terms that come up repeatedly. Reading it first makes the rest easier.

Term	Meaning	Everyday analogy
International export control regime	An international understanding under which participating states align how they control exports of arms and of goods that also have military uses. It is not a treaty	Several neighborhood associations agreeing on lending rules
COCOM	A Cold War arrangement. It ended in 1994	A residents' agreement under which any exception needs every household's approval
Wassenaar Arrangement (WA)	COCOM's successor, covering conventional arms and dual-use items. 42 participating states	A shared checklist, with each household deciding whether to lend
Consensus	Deciding when no participating state objects. Not a majority vote	A meeting where one objection stalls the agenda
Dual-use items	Goods and technologies usable for both civilian and military purposes	A kitchen knife, useful for cooking but dangerous in the wrong hands
List control	Licensing for items specified by performance or specification, regardless of destination	A named list of items that may not leave without permission
National discretion	Each participating state decides, under its own law, whether to approve or deny an export	In the end, each household decides
Appended Table 1	The table in Japan's Export Trade Control Order that lists items under list control, from entry 1 to entry 16	Japan's version of the named list

The analogies are mine, offered to help you grasp the mechanics. The real systems are not literally built like neighborhood associations.

What COCOM was, from 1949 to 1994

COCOM stands for the Coordinating Committee for Multilateral Export Controls. It began in 1949. The U.S. State Department's published diplomatic records show that in a series of meetings in Paris in November 1949, representatives of Belgium, France, Italy, the Netherlands, the United Kingdom and the United States agreed to set up a permanent group to handle strategic export control on a multilateral basis. Canada, Norway and Denmark soon joined, and a high-level consultative group met in Paris in January 1950. A coordinating committee, made up of representatives of the participating countries based in Paris, carried on the day-to-day work.¹

Membership grew. A report of the U.S. House of Representatives says COCOM was created in 1949 by the United States, the NATO countries other than Iceland and Spain, and Japan, with Spain and Australia joining later. At the end there were 17 members. The countries it targeted were the Soviet Union, the other Warsaw Pact states and the People's Republic of China.² Japan's government told the Diet in 1986 that it joined in 1952.³

Three features defined how it worked. The first was the control lists. The Congressional Research Service (CRS) explains that COCOM maintained three lists, covering industrial items, atomic energy items and munitions, and members built them into their own export control systems.⁴ For Japan, the director general of the trade bureau at the Ministry of International Trade and Industry told the Diet in 1986 that COCOM-related controlled items were set out in Appended Table 1 of the Export Trade Control Order as 164 items.³

The second feature was unanimity. CRS describes COCOM as operating by consensus, which in practice gave any member a veto over another member's export. It had no treaty basis and no special standing in international law.⁴ The third was the exceptions procedure. Sometimes a member wanted to export an item that was on the list to a particular country. According to the 1986 testimony, there were two kinds of exceptions. A general exception required the unanimous approval of COCOM. An administrative exception covered minor items and left the judgment to each government.³ In 1988, a Foreign Ministry official told the Diet that an exceptional export is possible if it is approved unanimously under the understanding among members, and that Japan often asks for such approval.⁵

Using the analogy once more, imagine every household in a district agreeing not to lend a certain item to a particular house, and a household that really wants to lend it must obtain everyone's consent. One objection is enough to block it. The details of how COCOM ran were not public either. The same Foreign Ministry official began his 1988 answer by saying that, under the members' understanding, COCOM's operation would not be disclosed beyond a certain limit.⁵

The point to hold on to is that COCOM screened cases in advance. An export of a controlled item to the communist bloc could not be completed on one country's judgment alone, and the committee had to agree. That feature is also why the arrangement could not simply continue once the Cold War ended.

The Toshiba Machine case and the end of COCOM

When people talk about the COCOM era in Japan, the 1987 Toshiba Machine case is hard to avoid. A machine tool capable of simultaneous nine-axis control was described as a two-axis machine, a certificate of non-applicability was obtained, and the machine went to the Soviet Union. I have written a separate article that traces the case, the verdict, the amendment of Japan's foreign exchange law and the U.S. reaction through Diet records, so I will not repeat it here. For the details, see our article that follows COCOM-era violations through Diet records up to today's FEFTA violations. What matters here is that the case changed Japanese law. The amendment promulgated in September 1987 raised the maximum criminal penalty from three years to five years, and the maximum administrative sanction from one year to three years (the supporting Diet records are in the footnotes of the linked article).

COCOM itself ended six years after the case. According to the history on the Wassenaar website, after the Cold War ended, the former COCOM members recognized that an East-West focus was no longer an appropriate basis for export controls. At a high-level meeting in The Hague on November 16, 1993, representatives of the 17 COCOM member states agreed to terminate COCOM and establish a new multilateral arrangement. The decision was confirmed at a meeting in Wassenaar on March 29 and 30, 1994, and COCOM ceased to exist on March 31, 1994.⁶

What happened in between is worth noting. The website says the participating states agreed to keep using the COCOM control lists as a basis for national export controls until the new arrangement could be established. The former COCOM cooperating countries, namely Austria, Finland, Ireland, New Zealand, Sweden and Switzerland, joined the preparations.⁶ CRS describes the transition as a move to national discretion, under which each country decides what to export and no country can veto another's decision.⁴

How the Wassenaar Arrangement works, and how it differs from COCOM

The Wassenaar Arrangement takes its name from a suburb of The Hague in the Netherlands, where agreement to start a new kind of multilateral cooperation was reached in 1995. The official website records that at a high-level meeting in September 1995, Russia, the Czech Republic, Hungary, Poland and Slovakia were welcomed as participating states, and that agreement to establish the arrangement came on December 19, 1995. The secretariat was placed in Vienna, and the first plenary meeting took place there on April 2 and 3, 1996. Some issues were unresolved, so the meeting was suspended. It resumed on July 11 and 12, and the 33 founding members, including Bulgaria and Ukraine, finally agreed on the basic document, the Initial Elements. The new control lists and information exchange were implemented from November 1, 1996.⁶

What exactly did they agree to? The purposes section of the Initial Elements says the arrangement contributes to regional and international security and stability by promoting transparency and greater responsibility in transfers of conventional arms and dual-use goods and technologies, and that participating states will seek through their national policies to ensure such transfers do not contribute to military capabilities that undermine those goals. The same section says the arrangement will not be directed against any state or group of states and will not impede bona fide civil transactions.⁷ That starting point differs from COCOM, which was aimed mainly at the communist bloc.

On governance, the decision-making body is the plenary, which normally meets once a year in December in Vienna. The chair rotates annually among participating states, and all decisions are taken by consensus.⁶ The 29th plenary was held on December 3 and 4, 2025, chaired by Ambassador Kaifu Atsushi of Japan. The December 2026 plenary will mark the arrangement's 30th anniversary.⁸

Who decides on an actual export? The Initial Elements say the decision to transfer or deny transfer of any item is the sole responsibility of each participating state, and that all measures are taken in accordance with national legislation and policies and implemented on the basis of national discretion.⁷ Unlike COCOM, an export does not depend on other countries' consent. Instead, participating states notify each other of licences denied to non-participating states. A notified denial does not oblige other states to deny similar transfers. For the most sensitive categories, however, a state that approves a licence for an essentially identical transaction that another state denied within the last three years must notify the others, preferably within 30 days and at the latest within 60 days.⁷

The control lists come in two parts. The Munitions List covers items specially designed for military use, such as tanks, military aircraft, warships, missiles and firearms, and according to the website it has 22 main entries. The List of Dual-Use Goods and Technologies has nine categories, namely special materials, material processing, electronics, computers, telecommunications and information security, sensors and lasers, navigation and avionics, marine, and aerospace and propulsion, along with annexes for sensitive and very sensitive items.⁶

One point is easy to misread. The Wassenaar Arrangement is not a treaty. It does not legally bind participating states, and compliance with the lists is voluntary.⁹ How each state builds the lists into its laws, and how it applies them, is left to national procedures. The official FAQ says the scope of controls is determined by the WA lists, but practical implementation varies from country to country in accordance with national procedures.⁶ Here is how the two compare.

Item	COCOM	Wassenaar Arrangement
Creation	Agreed in 1949, coordinating committee active from 1950	Agreed in 1995, operating from 1996
Main target	Communist countries	Not directed against any state or group of states
Members	17 at the end	42 (33 at the start)
Exceptions	General exceptions needed unanimous approval	Each state alone decides on exports and notifies denials
Openness	Operating details not public	Control lists and chair statements public, deliberations confidential
Legal status	Not based on a treaty	A political understanding, not a treaty

From Japan's side, the biggest change is that exporters stopped waiting for other countries' consent and began to decide for themselves. The current practice in Japan, where the exporter determines whether an item falls under the lists and keeps the grounds on record, rests on this national discretion. If you want to start with how list control and the catch-all control that supplements it relate, our guide to the difference is a good entry point.

How the four regimes divide the work, and how they map to Appended Table 1

Wassenaar is not the only international framework. Japan's Ministry of Economy, Trade and Industry (METI) lists four international export control regimes. As of July 28, 2025, METI's summary is as follows.¹⁰

Regime	Abbreviation	Area	Started	Participants
Nuclear Suppliers Group	NSG	Nuclear weapons	1978 (as METI states it)	48 countries
Australia Group	AG	Chemical and biological weapons	1985	42 countries and the EU
Missile Technology Control Regime	MTCR	Missiles	1987	35 countries
Wassenaar Arrangement	WA	Conventional arms and dual-use items	1996	42 countries

Each has a different origin. METI says the NSG began against the background of India's 1974 nuclear test, with the aim of controlling exports of equipment that could be used to make nuclear weapons. The AG began in 1985 against the background of chemical weapons use in the Iran-Iraq War, and the MTCR began in 1987 after missile development became active in the early 1980s.¹¹ The NSG's own explanation says its first guidelines were published by the International Atomic Energy Agency in 1978, and it dates the group itself to 1975. The years differ because people start counting from different points, the nuclear test, the start of consultations or the publication of guidelines.¹² The table follows METI's figures.

The MTCR states its aim as restricting the proliferation of missiles, rocket systems and unmanned air vehicles capable of carrying a 500 kilogram payload at least 300 kilometres, along with related technology.¹³ The NSG applies two sets of guidelines to nuclear and nuclear-related exports. They are not legally binding, but participating governments commit to apply them through national legislation.¹²

You might wonder whether these four are separate worlds. The Wassenaar founding document itself says the arrangement will complement and reinforce, without duplication, the existing regimes for weapons of mass destruction and their delivery systems.⁷ The chair's statement for 2025 notes that the arrangement maintained informal technical contacts with the MTCR and the NSG at expert level on control list issues.⁸ The roles are divided, but states talk to each other about items that sit on the border.

So where do these four appear in Japanese law? In Appended Table 1 of the Export Trade Control Order. I explain each entry in our guide to entries 1 to 16, so here I only trace the essentials. Checking the table on the e-Gov law database, entry 1 covers arms such as firearms and ammunition, entry 2 covers nuclear materials and reactors, entry 3 covers substances that are raw materials for chemical weapons, and entry 3-2 covers organisms and toxins that are raw materials for biological weapons. Entry 4 covers rockets and other missile-related goods. Entries 5 onward list dual-use goods such as materials, electronics, computers, telecommunications, sensors, navigation, marine items and propulsion. Entry 16 sets out the catch-all control, which covers what the list entries do not.¹⁴ METI's December 2023 summary of amendments reflecting regime agreements sorts its changes by entry number and regime, for example "arms-related (entry 1) (WA)," "nuclear-related (entry 2) (NSG)" and "biological weapons-related (entry 3-2) (AG)." It also labels entries 5, 8, 10, 13 and 15 as WA.¹¹ The table below summarizes this.

Entry	Examples	Corresponding regime	Basis
1	Firearms, military equipment	WA (Munitions List)	Stated in METI's document
2	Nuclear materials, reactors	NSG	Stated in METI's document
3	Chemical weapon precursors	AG	My own reading of the entry and the AG's purpose
3-2	Organisms and toxins for biological weapons	AG	Stated in METI's document
4	Rockets	MTCR	My own reading of the entry and the MTCR's purpose
5, 8, 10, 13, 15	Advanced materials, computers, sensors and lasers, propulsion, sensitive items	WA (Dual-Use List)	Stated in METI's document

This does not mean each regime maps to an entry one to one. The mapping is a guide at the level of entries, including those not in the table, and the origin of each individual item has to be checked against the law and METI's documents. The guide I linked above reads the entries one by one with item examples.

One more clue for reading other countries' systems. In the U.S. Commerce Control List of the Export Administration Regulations, the last three digits of an Export Control Classification Number (ECCN) show the reason for control. Numbers from 000 to 099 are national security, 100 to 199 missile technology, 200 to 299 nuclear nonproliferation, 300 to 399 chemical and biological, and 600 to 699 correspond to the Wassenaar Munitions List.¹⁵ Japan's entry numbers and America's ECCNs look different, but the same international regime categories lie underneath both. If a supplier tells you an item is 3A001 and you can read that the leading 3 is the electronics category and the trailing 001 is a national security control, you have a way into comparing it with Japan's entry numbers.

How agreements become Japanese law

What a regime plenary decides does not become Japanese law by itself. Each year, METI amends ordinances, notices and circulars to reflect the agreements. The December 2023 document states the purpose this way. To prevent the proliferation of weapons of mass destruction and the excessive accumulation of conventional arms, the targets of export control are agreed in meetings of the international regimes in which major countries participate. To secure those agreements, Japan specifies the technologies and goods that require permission under Article 25, paragraph 1 or Article 48, paragraph 1 of the Foreign Exchange and Foreign Trade Act in the Foreign Exchange Order's appended table, Appended Table 1 of the Export Trade Control Order, and the Goods and Technologies Ordinance.¹¹

Tracing the flow, a regime plenary first agrees on additions, deletions and changes of specification. The WA plenary meets in December. METI then drafts and promulgates the ordinance amendments, and they take effect after a grace period. The 2023 round was promulgated on December 1, 2023 and took effect on February 1, 2024.¹¹ The 2025 round was promulgated on November 14, 2025, with some parts effective on November 15 and the review of controlled goods effective on February 14, 2026.¹⁶ From an international decision to Japanese enforcement, expect roughly a year.

The changes are not only tightening. The 2023 amendments mixed deregulation, tightening and clarification in the same round. In advanced materials, for instance, the specification for a vibration-damping liquid was narrowed, which is a relaxation, while in biological weapons-related items, bacterial names were changed and specifications for genetically modified products were added.¹¹ The 2025 amendments added equipment for synthesizing peptides, powders of high-entropy alloys and similar items as controlled goods for all destinations.¹⁶

Taiwan offers a parallel. On November 17, 2025, Taiwan's Administration of Foreign Trade under the Ministry of Economic Affairs announced a proposed amendment of its dual-use and military goods control lists, citing as its reason that the Wassenaar Arrangement and other international norms had updated their control lists.¹⁷ Many countries carry the agreements into their own systems, each in its own way and on its own schedule. If you have counterparties in Taiwan, finishing the Japanese procedure does not guarantee that no other permit is needed on the other side.

This mechanism has a practical consequence. A classification record is not finished once it is written. Items under list control are amended nearly every year. A product you judged "not applicable" last year can become applicable under the amended specification, and the reverse also happens. Recording the date of each determination and the version of the law you relied on pays off later. I covered how list control and catch-all control relate in the guide linked earlier.

"Dysfunction" claims, and national measures

A framework that decides by consensus is strong on topics everyone can agree on and slow on topics they cannot. This point shows up in the arrangement's own documents and in national materials, in a neutral form.

Start with the official chair statements. The 2025 statement records that the plenary updated and clarified control list entries covering lasers, imaging sensors and cameras, seabed surveying equipment, parachutes and paragliders, and ceramic composite materials. It also removed entries covering certain temperature sensors and underwater vision and light systems that are now deemed to have no military significance, and it updated the Best Practice Guidelines on Internal Compliance Programmes.⁸ The 2024 statement records new controls on sub-orbital spacecraft and on technologies for producing metal alloy powders.⁸ The official statements simply list what was agreed. They do not mention topics on which no agreement was reached or which state objected, because deliberations are confidential.

Outside analysis, on the other hand, does point to the difficulty of consensus. In a 2023 report, CRS wrote that because of difficulties in reaching consensus among the members of existing export control arrangements, some policymakers and experts have advocated that the United States coordinate export control policy with smaller groups of like-minded states. The same report explains that the Wassenaar Arrangement is open to virtually any state and has a broad membership that includes former Soviet states, and that admission is by consensus.⁹ Japan's Subcommittee on Security Trade Control also set out a direction in its April 2024 interim report that stresses effectiveness and fairness through international cooperation, according to METI's summary. I cite that from another article of mine where I checked it, and I could not retrieve the original again for this piece.

I do not read this as a question of blaming any particular country. Forty-two states with different security priorities, industrial circumstances and regional situations must agree unanimously on a technology control list. In fields where technology moves in months, a once-a-year plenary will struggle to keep up, and that follows from the design. The participants include a wide range of countries, including former Soviet states, but the official documents do not publish who voted which way. Rather than passing judgment, the practical takeaway is simple. In a consensus framework, an item is not decided unless every participant agrees.

In this situation, countries rely on national measures and coordination among like-minded states. The United States set up a framework for like-minded countries in September 2024, the EU added its own list in 2025, and Japan revised its catch-all control in October 2025. The primary sources for each are in the footnotes of the articles below. METI's summary of the November 2025 amendment, which I discussed above, also lists "amendments that reflect the international situation as a responsible technology-holding country" alongside the regime agreements.¹⁶ I treat each of these from a different angle elsewhere. For the whole picture of the Wassenaar slowdown and national responses, see our article on Wassenaar dysfunction and what each country does. For the design of the EU's own list, see our article on the EU's independent controls. For what the phrase "level playing field" means in these debates, see our piece that checks the term against primary sources.

To be clear, Wassenaar has not ended. The 2025 plenary took place, the lists were updated, and 2026 brings the 30th anniversary. I think it is closer to the truth to say its role is shifting toward a complementary reference framework.

Common misunderstandings, and what this means for your own classification

Let me test the ideas above against the points where beginners most often stumble.

"COCOM and Wassenaar are the same organization under a new name" is half right. The core membership and the foundation of the control lists carried over. The website says the COCOM lists served as the national basis until the new arrangement was ready.⁶ But the design is different. The main target changed from the communist bloc to no named state, and the exceptions mechanism moved from unanimous approval to national discretion plus notification.

"If an item is on the Wassenaar list, the rule is the same everywhere in the world" is also wrong. A WA agreement takes effect only when a country builds it into its laws, and the timing and scope vary by country. The same product can have different outcomes in Japan, the United States and Taiwan.

"If an item is not on the list, I do not have to check anything" is a misunderstanding as well. List control looks at performance and specification, and even a dual-use item that is not on the list can require a license if the end use or the counterparty raises concern. I explain that complementary mechanism in our beginner guide to catch-all control.

Finally, what does all this have to do with your own work? In practice, knowing the regimes helps in four situations.

The first is when a counterparty gives you a foreign classification number. U.S. ECCNs and Taiwan's control numbers rest on the same international regime categories as Japanese entry numbers. Once you can read the numbers, you stop taking a foreign determination at face value and start seeing which entry of Appended Table 1 to compare it with. A foreign classification number can never stand in for a Japanese determination, however. For exports from Japan, the exporter makes the determination itself under Japanese law.

The second is preparing for annual list changes. If you know the WA plenary meets in December and that Japanese enforcement follows between the start and the end of the next year, you can plan when to begin reviewing your records. Even naming one person to watch METI's amendment notices makes a difference.

The third is internal rules. In 2025 the Wassenaar Arrangement updated its guidelines on internal compliance programmes for dual-use items.⁸ That tells you internationally that a company's own control system is treated as part of the framework.

The fourth is keeping track of overseas developments. The more national measures there are, the more laws you must reference. This is the part that becomes hard to follow by hand, and where I think a tool such as TRAFEED can help. The final classification decision remains with your company's export control officer. A tool widens the range of what you check and helps you keep the grounds for your judgment on record, and that is all it does.

The biggest payoff of knowing this history, I think, is seeing that Appended Table 1 and the yearly amendments in front of you are not accidents but the continuation of a long design built after the Cold War. As a small first step, open your copy of Appended Table 1, pick the entry closest to one of your products, and find out which regime's agreement it comes from. That alone changes how you read the law.

If you want to take stock of your overall export control setup, take a look at the TRAFEED service page, or reach out through a consultation request.
