North Korea is willing to engage in talks with the U.S. under the right conditions, a senior North Korean diplomat revealed Saturday.

“We’ll have dialogue if the conditions are there,” Choe Son Hui, head of U.S. affairs for the North Korean foreign ministry, told South Korea’s Yonhap News Agency in Beijing. Choe had just concluded Track 1.5 discussions with former U.S. officials in Norway and was in the process of returning to Pyongyang at the time of the interview.

Choe did not specify what conditions would be needed for a dialogue with the Trump administration.

President Donald Trump told Bloomberg News earlier in May he would be willing to meet with North Korean dictator Kim Jong Un.
