He commended the “determination and diplomacy” shown by the leaders of North Korea, formally known as the Democratic People’s Republic of Korea (DPRK), and South Korea, formally known as the Republic of Korea.

South Korea’s President, Moon Jae-in, became the first leader from the south to travel to the North Korean capital in years on Monday, and at the conclusion of the three days of talks with his northern counterpart, Kim Jong-un, both sides described it as a positive step towards peace.

“The commitments reflected in the joint statement include important military confidence-building measures and a commitment by the DPRK to dismantle missile engine testing infrastructure in the presence of experts from related countries”, said the Secretary-General, in a statement issued by his Spokesperson, adding that “now it is time for concrete action”.
 
Guterres called “for unity of the international community to support the parties in their endeavours towards sustainable peace, security and complete and verifiable denuclearization on the Korean Peninsula in accordance with relevant Security Council Resolutions”.

He also reiterated the commitment and readiness of the United Nations system “to further assist the parties in any way they deem appropriate”.

This Pyongyang joint Declaration came three days after the UN political affairs chief, Rosemary di Carlo, told the Security Council that the International Atomic Energy Agency (IAEA) reported having observed in May nuclear signatures consistent with the continued operation of a plutonium production reactor, radiochemical laboratory and alleged uranium enrichment facility in Yongbyon, North Korea.
