Seoul, Oct 15 (IANS): The top nuclear envoys of South Korea, the US and Japan will meet in Washington next week to discuss joint efforts to bring North Korea back to dialogue, the Foreign Ministry in Seoul announced on Friday.

The planned talks among South Korea's chief nuclear negotiator, Noh Kyu-duk, and his US and Japanese counterparts, Sung Kim and Takehiro Funakoshi, come as Seoul is stepping up diplomacy to salvage its peace drive following a recent series of North Korean missile launches, including a hypersonic one last month, reports Yonhap News Agency.

Noh and Kim are expected to meet bilaterally on October 18 and join a trilateral meeting with Funakoshi the following day.

Noh is also likely to hold two-way talks with Funakoshi on October 19.

The three envoys held their last in-person talks in September in Tokyo, as they have been exploring ways to encourage Pyongyang's return to dialogue, including humanitarian and other incentives.

Next week's talks are expected to touch on President Moon Jae-in's recent proposal for the declaration of a formal end to the 1950-53 Korean War, which Noh has said is the most effective among confidence-building measures.

They could also discuss humanitarian support for the North and the recent reactivation of inter-Korean communication lines, which has raised cautious hope for a cross-border thaw.

"Through the visit to Washington this time, we expect that there will be in-depth consultations over cooperation among the three countries for the complete denuclearization and the establishment of lasting peace on the Korean Peninsula," the Ministry said in a statement.

Nuclear talks between Washington and Pyongyang have remained stalled since the Hanoi summit in 2019 between then US President Donald Trump and North Korean leader Kim Jong-un ended without a deal.

On Thursday, Noh also met Deputy Foreign Minister Igor Morgulov in Russia, calling for Moscow's cooperation in persuading Pyongyang to return to dialogue.
