US Special Representative for North Korea Policy Sung Kim will visit Seoul this week for talks on ways to restart dialogue with the reclusive North, including an end-of-war declaration, the US diplomat said Monday.

Kim's trip to Seoul will follow his meeting with his South Korean and Japanese counterparts, Noh Kyu-duk and Takehiro Funakoshi, respectively, here in Washington this week.

"Special Representative Noh and I also discussed the end of war proposal, and I look forward to continuing those discussions and other issues of mutual concern when I'm in Seoul later this week," the US diplomat said of his meeting with Noh at the State Department.

"Special Representative Noh and I had an excellent meeting this afternoon in advance of tomorrow's trilateral meeting with Japanese Director-General Funakoshi," he added.

South Korean President Moon Jae-in proposed declaring a formal end to the Korean War during the UN General Assembly in New York last month as a way of bringing North Korea back to the dialogue table and resuming its denuclearization process.

"A considerable amount of today's discussions were devoted to in-depth discussions on end-of-war declaration," Noh said. "I believe the US' understanding of our end-of-war declaration proposal has deepened through a series of our recent discussions."

The South Korean and US nuclear envoys last met at the end of last month in Jakarta, where Kim is concurrently serving as US ambassador.

North Korea remains unresponsive to US overtures for dialogue and has stayed away from denuclearization talks with the US since 2019.

Noh said he and Kim discussed ways to build trust with North Korea.

"(We) discussed various ways of engagement, such as humanitarian assistance for the North and other trust-building measures to help quickly restart dialogue and diplomacy," the South Korean official said in a joint press event with his US counterpart.

Kim said the US remains open to dialogue with North Korea.

"The US continues to reach out to Pyongyang to restart dialogue. Our intent remains the same. We harbor no hostile intent towards the DPRK, and we are open to meetings without preconditions," he said, referring to North Korea by its official name, the Democratic People's Republic of Korea.

"We are prepared to work cooperatively with the DPRK to address areas of humanitarian concern. The US supports the provision of humanitarian aid, consistent with international standards for access and monitoring, to the most vulnerable," Kim added.

Still, the US special representative emphasized the need to maintain international pressure on the North.

"Even as we remain open to dialogue, we also have a responsibility to implement the UN Security Council resolutions addressing the DPRK," he said.

"Furthermore, consistent with the Biden-Harris administration's focus on human rights, we will continue to advocate for the human rights of the North Korean people and call for an immediate resolution of the abduction issue," he added, referring to the issue of Japanese nationals believed to have been abducted by the North.
