The top nuclear envoys of South Korea and the United States held a telephone conversation Friday and discussed the outcome of a South Korean delegation's recent trip to North Korea.

The delegation led by Chung Eui-yong, Seoul's national security advisor, made a one-day trip to Pyongyang on Wednesday to arrange a third summit between President Moon Jae-in and North Korean leader Kim Jong-un. It later announced that Moon will travel to Pyongyang from Sept. 18-20 to meet with Kim.

Lee Do-hoon, representative for Korean Peninsula peace and security affairs at Seoul's foreign ministry, spoke with his U.S. counterpart Stephen Biegun via phone and shared the outcome of the delegation's trip to the North, according to the ministry.

It was the first such conversation between the two since Biegun took office last month.

During the conversation, they vowed close cooperation in making progress in denuclearizing talks with North Korea and building lasting peace and prosperity on the Korean Peninsula, the ministry said.

The discussion came days before Biegun, a former Ford Motor executive, will make his first trip to South Korea early next week.

Nuclear talks have been all but stalled since the U.S. and North Korea held their historic summit in June, at which they agreed to work toward the complete denuclearization of the Korean Peninsula.

Expectations are growing that the forthcoming inter-Korean summit could help break the logjam and kick-start the stalemated process.
