The new U.S. envoy to North Korea is traveling to South Korea, Japan and China to discuss issues on the Korean Peninsula.
It will be envoy Glyn Davies' first trip to the region since he took up the post. He was previously the U.S. ambassador to the International Atomic Energy Agency.
The State Department said Monday that Davies will be accompanied by Clifford Hart, U.S. envoy to the stalled six-nation talks on North Korea's nuclear program. They arrive in Seoul Wednesday.
The U.S. and North Korea have held two rounds of bilateral talks since July on the nuclear issue but without signs of progress.
Last week North Korea reported rapid progress on work to enrich uranium and build a light-water nuclear power reactor.
