The visit by Wu Dawei, China's special representative for Korean Peninsula affairs, comes after North Korea said it successfully tested its first H-bomb on January 6.
China has said it firmly opposes the nuclear test and supports a new UN resolution and sanctions. But nearly one month after the test, there is no sign of an agreement among the US, its allies and China on exactly what sanctions should be adopted.
Pak Song Il, deputy director of the America department at the North Korean Foreign Ministry, greeted Wu in the VIP area of Pyongyang's airport.
Wu Dawei met the US State Department's special representative for North Korea policy, Sung Kim, in Beijing last week.
