Sung Kim, the US ambassador to the Philippines, held talks with North Korean officials over the weekend in what appears to be the first face-to-face meeting between representatives of the two countries since President Donald Trump and Kim Jong Un’s summit last month, a report said Monday.

Sung Kim, who has played a critical role in the negotiations with Pyongyang, led a delegation that met with their North Korean counterparts in Panmunjom, a village on the demilitarized zone separating the two countries, the Washington Post reported.

The talks focused on taking the next step in carrying out the declaration signed by Trump and Kim during the Singapore summit June 12.

“Our goal remains the final, fully verified denuclearization of the DPRK, as agreed to by Chairman Kim in Singapore,” the State Department said in a statement, using the initials of the country’s official name, the Democratic People’s Republic of Korea.

An ambassador to South Korea between 2011 and 2015 who previously negotiated with Pyongyang over its nuclear arsenal, Sung Kim also met with North Korean officials in May in the run-up to Singapore.

Secretary of State Mike Pompeo is expected to meet with North Korean officials this week to continue negotiations — even as news reports citing the US intelligence community say that North Korea does not intend to abandon its nuclear arsenal.

National security adviser John Bolton said the US could dismantle the regime’s stockpile in a year if Kim would cooperate.

“I’m sure that the secretary of state, Mike Pompeo, will be discussing this with the North Koreans in the near future, about, really, how to dismantle all of their WMD and ballistic missile programs in a year,” Bolton said on CBS’ “Face the Nation” on Sunday. “If they have the strategic decision already made to do that and they’re cooperative, we can move very quickly.”
