A senior U.S. envoy on the North Korean nuclear program was to arrive in South Korea later Monday for talks on the situation of the Korean Peninsula and to align the allies' policy on Pyongyang, officials here said.

During a two-day visit to Seoul, U.S. Special Representative for North Korea Policy Glyn Davies was scheduled to meet his South Korean counterpart Cho Tae-yong and other senior officials here to assess the current situation on the Korean Peninsula and discuss ways to coordinate the allies' policy toward Pyongyang, they said.

North Korea has been reaching out to both South Korea and the U.S. after mounting tensions earlier this year by conducting its third nuclear test.

However, South Korea, the U.S. and Japan have shown little appetite to the overtures, while calling on it to demonstrate its seriousness about denuclearization through concrete actions for the six-party talks to resume.

The six-nation talks aimed at ending the North's nuclear program have been stalled since late 2008. The multilateral forum involves the two Koreas, the U.S., China, Russia and Japan.

"Also on the table will be how Seoul and Washington coordinate their stance on China's recent proposal to hold an informal meeting with officials from the six countries," a diplomatic source here said, requesting anonymity.

As part of its recent efforts to resume the multilateral talks, China last month made such a proposal for the so-called Track 1.5 meeting in Beijing on Sept. 18.

The meeting, to be organized by the China Institute of International Studies, affiliated with its foreign ministry, coincides with the eighth anniversary of a 2005 agreement when the six nations achieved their first breakthrough in resolving the North's nuclear standoff during the multilateral dialogue.

Davies plans to visit China and Japan to meet with counterparts before returning home on Friday, according to officials. (Yonhap News)
