The new U.S. special representative for North Korea, Sung Kim, is in Seoul for talks with his South Korean and Japanese counterparts.
This is Kim's first trip to Seoul since taking his new job, and he'll be meeting on Monday one-on-one with South Korea's top nuclear envoy, Noh Kyu-duk, then joining a three-way meeting with Japan's nuclear envoy, Takehiro Funakoshi.
They're expected to discuss the new U.S. policy on North Korea, which the Biden administration describes as "practical" and "calibrated."
Their talks come after North Korea wrapped up a meeting of its Workers' Party Central Committee, led by Kim Jong-un.
There Kim said on Friday that the North will be ready for both dialogue and "confrontation" in an international situation he described as "fast changing."
