U.S. Secretary of State Mike Pompeo and high-ranking North Korean official Kim Yong Chol enter a second day of meetings in New York on Thursday as they try to settle nuclear weapons disagreements and set the stage for a historic summit between their two leaders.

South Korean media also reported that a North Korean delegation arrived in Singapore on Monday night for likely summit preparations with U.S. officials.

The bigger worry among the experts and analysts is that the summit in Singapore might actually happen, Jackson Proskow says.
