The ASEAN Foreign Ministers deplore and express grave concerns over the nuclear test conducted by the Democratic People’s Republic of Korea (DPRK) on 3 September 2017, which is again in violation of the relevant United Nations Security Council (UNSC) resolutions and goes against international efforts on non-proliferation and disarmament of weapons of mass destruction. This is the sixth nuclear test by the DPRK. The DPRK’s latest actions, including its recent missile tests and two earlier nuclear tests last year, have heightened tensions in the Korean Peninsula and threatened regional peace and security. The DPRK’s disregard of international law as well as the grave concerns of the international community seriously calls into question the country’s sincerity in having meaningful dialogue on the real issues facing the Korean Peninsula.
