Reference excerpt

The Southeast Asian Nuclear-Weapon-Free Zone Treaty (SEANWFZ), or the Bangkok Treaty of 1995, is a nuclear weapons moratorium treaty between 11 Southeast Asian member-states under the auspices of the ASEAN: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam and Timor-Leste. It was opened for signature at the treaty conference in Bangkok, Thailand, on 15 December 1995 and it entered into force on March 28, 1997 and obliges its members not to develop, manufacture or otherwise acquire, possess or have control over nuclear weapons. The Zone is the area comprising the territories of the states and their respective continental shelves and Exclusive Economic Zones (EEZ); "Territory" means the land territory, internal waters, territorial sea, archipelagic waters, the seabed and the sub-soil thereof and the airspace above them. The treaty includes a protocol under which the five nuclear-weapon states recognized by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), namely China, the United States, France, Russia and the United Kingdom (who are also the five permanent members of the United Nations Security Council) undertake to respect the Treaty and do not contribute to a violation of it by State parties. None of the nuclear-weapon states have signed this protocol.

Background

The groundwork of the establishment of the future Southeast Asian Nuclear-Weapon-Free Zone Treaty (SEANWFZ) was started on November 27, 1971, when the 5 original members of the Association of Southeast Asian Nations (ASEAN), Indonesia, Malaysia, Philippines, Singapore, and Thailand, met in Kuala Lumpur, Malaysia and signed the declaration on ASEAN's Zone of Peace, Freedom and Neutrality (ZOPFAN). One of the targets of ASEAN was also the establishment of SEANWFZ. However, due to the political atmosphere at that time, including rivalries among the members and conflicts in the region and the Cold War, it was less feasible then to establish SEANWFZ. Thus the formal proposal for establishing a nuclear-free region was delayed until the 1990s, after the Cold War ended and conflicts were settled, and the member states renewed the denuclearization efforts. After conducting negotiations and finalizing the treaty for SEANWFZ by an ASEAN working group, the SEANWFZ treaty finally signed by the heads of government from 10 ASEAN member states in Bangkok on December 15, 1995. The treaty took effect on 28 March 1997 after all but one of the member states have ratified it. It became fully effective on 21 June 2001, after the Philippines ratified it, effectively banning all nuclear weapons in the region. In 2014 at the Meeting of the Commission for the Treaty on the SEANWFZ, the Ministers reviewed the progress on the implementation of the 2013-2017 Plan of Action to Strengthen the SEANWFZ Treaty, while reaffirming their commitment to preserve Southeast Asia as a Nuclear-Weapon Free Zone.

Listing of parties

Protocol The SEANWFZ treaty has a protocol that is open to signature by the five recognized nuclear-weapon states: China, France, Russia, the United Kingdom, and the United States. The protocol commits those states not to contribute to any violation of the treaty and not to use or threaten to use nuclear weapons within the zone. As of April 2015, none of the five has signed the SEANWFZ protocol, but in November 2011 they agreed with ASEAN states on steps that would enable them to do so.

Worked examples

Example 1 — a first encounter with Southeast Asian Nuclear-Weapon-Free Zone Treaty

Start with the simplest possible case. Write down what Southeast Asian Nuclear-Weapon-Free Zone Treaty claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Southeast Asian Nuclear-Weapon-Free Zone Treaty before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Southeast Asian Nuclear-Weapon-Free Zone Treaty ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Southeast Asian Nuclear-Weapon-Free Zone Treaty

In research: Southeast Asian Nuclear-Weapon-Free Zone Treaty appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Southeast Asian Nuclear-Weapon-Free Zone Treaty in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Southeast Asian Nuclear-Weapon-Free Zone Treaty is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1995 in Thailand, ASEAN treaties, Nuclear weapons governance, so understanding it makes those chapters shorter.
In everyday life: Look for Southeast Asian Nuclear-Weapon-Free Zone Treaty outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
