China’s Nuclear Deception: The Treaty That Would Handcuff America’s Military
China announced this week its willingness to “take the lead” in signing the Southeast Asia Nuclear Weapon-Free Zone Treaty, a move that comes while Beijing rapidly expands its nuclear arsenal.
The announcement, made by Chinese Foreign Ministry spokesperson Mao Ning, followed news that both China and Russia have agreed to become signatories to the decades-old Bangkok Treaty. The Bangkok Treaty, formally known as the Southeast Asia Nuclear Weapon-Free Zone Treaty (SEANWFZ), is a comprehensive nuclear disarmament agreement that creates one of the world’s most extensive nuclear-free zones.
America has not signed the Bangkok Treaty due to two primary objections, both rooted in concerns over limiting U.S. military operations and strategic flexibility in Southeast Asia. The treaty protocol requires nuclear-armed states to give unequivocal “negative security assurances”, a binding promise never to use or threaten to use nuclear weapons against treaty members. The U.S. opposes this requirement because it seeks to preserve strategic ambiguity in its nuclear doctrine.
Officials argue that such absolute assurances could conflict with alliance commitments, including defense treaties with the Philippines and Thailand, where the U.S. may need to retain the option of nuclear retaliation in response to chemical or biological attacks.
Additionally, U.S. nuclear strategy depends on the threat of nuclear use to deter not only nuclear but also large-scale conventional attacks. The treaty’s rigid language allows no exceptions, even in extreme scenarios, which Washington sees as a serious constraint on deterrence.
Past agreements have shown how security assurances can lead to unintended entanglements. A good example is the 1994 Budapest Memorandum, in which the U.S., UK, and Russia pledged security assurances to Ukraine, Belarus, and Kazakhstan in exchange for giving up their nuclear arsenals. These included commitments to respect sovereignty, avoid economic coercion, and respond to nuclear threats. When Russia invaded Ukraine in 2014 and again in 2022, those assurances triggered pressure for U.S. involvement.
If the United States signs the Bangkok Treaty protocol, comparable dynamics could unfold in Southeast Asia. For example, if China were to use military force against treaty parties such as the Philippines, Vietnam, or Malaysia, the U.S. could face strong pressure to intervene due to formal commitments made under the treaty. Similarly, in scenarios involving nuclear coercion, where China threatens to use nuclear weapons against ASEAN countries, the U.S. might feel obligated to respond, having extended security guarantees through the protocol.
