The Auspicious Republic of Xiaodong has over its history possessed several weapons of mass destruction. From 1908 to 1935 it maintained a chemical and biological weapons programme that was used in Senria during the Senrian front of the Great War before being dismantled after the end of the Great War. Since 1975 it has been one of the seven states in the world to have successfully developed and maintain nuclear weapons.

With nuclear development approved by Premier Li Zhaozheng in 1960 Xiaodong has steadily built a nuclear arsenal since 1965 when it refused to sign the Treaty of Shanbally after Senria developed nuclear weapons. Xiaodong launched its first nuclear test in 1975 during the Coastal Crisis - Housheng-1 whose max yield was 10 kilotons of TNT. Following the testing of Housheng-1 Xiaodong adhered to the so-called Harborough Protocols which effectively froze further Xiaodongese nuclear development and limited their ability to perform a second strike.

In 198X following [some crisis that Xiaodong blames Senria for] premier Sun Yuting restarted Xiaodong's nuclear programme effectively discarding the Harborough Protocols. Xiaodong performed several nuclear tests in the 1980's after the foundation of the Rongzhuo Strategic Protocol Organisation which resulted in Xiaodong to undergo an arms embargo and partial economic sanctions. The beginning of the Nuclear Arms Limitation and Non-proliferation Talks in 1986 saw Xiaodong agreeing to limit development of inter-continental ballistic missiles but refusing Senrian demands to take steps to de-nuclearise alongside the terms of the Treaty of Shanbally and the Harborough Protocols. Nuclear weapons development and testing continued throughout the 1990's until Xiaodong agreed to limit testing and missile development in 1999 and 2004. Development has continued since 2010 when Xiaodong conducted its last nuclear test.

Xiaodong maintains that it retains the right to launch a first-strike through a nuclear triad. Since 2012 it has outlined its own Baiqiao Principles where it has stated that it will streamline its nuclear force to maintain a "credible minimum defence" and that it is open to the idea of de-nuclearisation if it is done multilaterally, rejecting unilateral de-nuclearisation. Xiaodong has been in negotiation with the Atomic Energy Commission to allow them partial access to nuclear facilities in order to engage in nuclear commerce but these efforts have been limited.

Xiaodong is a member of [treaties that ban bio and chemical weapons].
