Myanmar is building a research nuclear reactor near Pyin Oo Lwin with help from Russia. It is one of the signatories of the nuclear non-proliferation pact since 1992 and a member of the International Atomic Energy Agency (IAEA) since 1957. The military junta had informed the IAEA in September 2000 of its intention to construct the reactor. In 2010 as part of the Wikileaks leaked cables, Myanmar was suspected of using North Korean construction teams to build a fortified surface-to-air missile facility. As of 2019, the United States Bureau of Arms Control assessed that Myanmar is not in violation of its obligations under the Non-Proliferation Treaty but that the Myanmar government had a history of non-transparency on its nuclear programs and aims.
