Seoul and Washington launched the working group in an inaugural meeting on Nov. 20 for "regular, systemic and formal" communication on North Korea policy as the allies increased efforts to coordinate their policies on their shared policy goal of denuclearizing North Korea.

The working group also held a videoconference meeting earlier this month.

The upcoming meeting will address both the ongoing standstill in denuclearization negotiations between Washington and Pyongyang and ways to get them started again, according to officials here.

No meaningful negotiations have taken place between the US and North Korea since US Secretary of State Mike Pompeo's visit to Pyongyang on Oct. 7.

Pompeo and his North Korean counterpart, Kim Yong-chol, were scheduled to hold talks on Nov. 8 in New York, but the meeting was postponed indefinitely as the two sides were wide apart over Pyongyang's demand for sanctions relief and Washington's demand for more denuclearization measures.

In this week's talks, South Korean and US officials are expected to share views on why North Korean leader Kim Jong-un's pledge to visit South Korea has fallen through and what effects it will have on the denuclearization process.

The two sides are also expected to discuss waiving sanctions for inter-Korean economic cooperation projects, such as the program to link the railways and highways of the two Koreas, whose ground-breaking ceremony is set for Dec. 26. (Yonhap)
