Kim Jong Un teased the possibility of improved relations with South Korea and vowed to expand "external relations" Thursday in his first remarks on the regime’s foreign policy since the election of U.S. President-elect Joe Biden, state-run media said Friday.

The North Korean leader broached the issue of “affairs with South Korea as required by the prevailing situation and the changed times” and “declared the general orientation and the policy stand of our party for comprehensively expanding and developing the external relations,” during the third day of a rare ruling party congress, the official Korean Central News Agency said.

It did not elaborate, and it was unclear if “external relations” referred to the United States and South Korea or China and Russia, which both have strong ties with Pyongyang.
