SEOUL, April 15 (Yonhap) -- South Korean Foreign Minister Yun Byung-se on Monday expressed a positive assessment of China's commitment to enforcing the latest U.N. sanctions against North Koreans linked to Pyongyang's nuclear and missile programs, saying Beijing is doing "rather well" in helping to restrain Pyongyang.

It was the first public assessment by Yun of China's role in reining in its wayward ally as the world is keeping a close eye on what North Korea's next move will be after weeks of warlike rhetoric and actions that have heightened tensions on the Korean Peninsula.
