The U.S. and South Korea are discussing "corresponding measures" to reward North Korea's steps toward denuclearization, South Korea's foreign minister said, as President Donald Trump and Kim Jong Un prepare for a possible second summit.

Foreign Minister Kang Kyung-wha told a news conference Wednesday in Seoul that the allies were reviewing various packages of incentives that Washington could bring to the table in the meeting. While Kang provided few details other than to say restarting stalled business projects were being discussed, the term can cover everything from sanctions relief to moves to formalize the end of the 1950-53 Korean War.

"Between South Korea and the United States, we are closely consulting what kinds of denuclearization measures should be followed and what the United States and the international community can do as corresponding measures," she said at a New Year's news conference. She said she expected nuclear talks to pick up speed.
