Stephen Bosworth, special representative for North Korea policy, will arrive in Seoul Sunday to meet with his South Korean counterpart to discuss resuming six-way talks aimed at solving North Korea's nuclear arms standoff, Yonhap News Agency reported.
The talks between South Korea, North Korea, the United States, Russia, Japan and China have been deadlocked since December 2008.
Bosworth and Wi Sung-lac, South Korea's chief nuclear envoy, reportedly are alike in believing Seoul and Washington could resume a series of talks with Pyongyang if North Korea mends fences with South Korea.
Relations between the two Koreas deteriorated after the sinking of the Cheonan, a South Korean warship, allegedly by a North Korean submarine near their western sea border in March.
Bosworth's last visit to Seoul was in February.
