The CTBTO at the Disarmament Conference in Jeju, Korea
The conference, which gathered experts from governments, international organizations, academic and research institutions and civil society, was hosted jointly by the Republic of Korea and the UN Office for Disarmament Affairs (see UN press release). A number of issues were addressed including the future of nuclear arms control and non-proliferation, the 2012 Seoul Nuclear Security Summit, and the nuclear programme of the Democratic People’s Republic of Korea (DPRK). The conference has been held annually since 2001.

“More and more states in Asia shall be mastering the nuclear fuel cycle. The Comprehensive Nuclear-Test Ban Treaty [CTBT] provides the last and clearly visible barrier between the peacefuland military uses of nuclear technology. This legal line needs to be drawn clearly and irrevocably.”

“The two North Korean nuclear tests were two too many...but by comparison, before the adoption of the CTBT in 1996 there were 400 to 500 every decade.”
Asia is of particular importance for the Comprehensive Nuclear-Test-Ban Treaty (CTBT), as five of the nine countries that have yet to sign and ratify before the CTBT can enter into force are from the region: China, the DPRK, India, Indonesia and Pakistan. The other four are Egypt, Iran, Israel and the United States.
