WASHINGTON, Nov. 19 (Xinhua) -- U.S. special envoy on the Democratic People's Republic of Korea (DPRK) will meet his South Korean counterpart here on Tuesday to discuss denuclearization and ties, the U.S. State Department said on Monday.

Stephen Biegun, U.S. special representative for the DPRK issue, will hold talks with Lee Do-hoon, special representative for Korean Peninsula peace and security affairs to talk about ongoing diplomatic efforts on the peninsula denuclearization, UN sanctions on Pyongyang and inter-Korean cooperation, said the department in a statement.

The high-level U.S.-South Korean officials' meeting came amid the stalled negotiations between the DPRK and the United States on the peninsula's denuclearization, as a meeting planned this month between U.S. Secretary of State Mike Pompeo and a senior DPRK official in New York was postponed.

The DPRK's official Korean Central News Agency (KCNA) reported on Friday that the country had decided to deport a U.S. citizen detained for illegally entering the country.

Pompeo said later on Friday that the United States appreciates the release of an American citizen by the DPRK. The State Department, however, declined to identify the citizen and did not give details about him.

Also on Friday, the KCNA reported that the DPRK top leader Kim Jong Un visited the testing ground of the Academy of Defence Science and supervised the test of a newly developed ultramodern tactical weapon.
