Delhi: South Korea`s Foreign Minister Yun Byung-se will speak with his Chinese counterpart Wang Yi by telephone at 1000 GMT on Friday, the foreign ministry in Seoul said in a text message to reporters.
Their teleconference comes in the wake of a North Korean nuclear test earlier this week that has increased tensions between the two Koreas.
South Korea`s foreign ministry had requested a phone call with Wang since directly after North Korea announced on Wednesday it had tested a hydrogen bomb, the South`s Yonhap News Agency said.
However, the phone call had been delayed due to China`s "internal scheduling", the report said.
China is the North`s main economic and diplomatic backer, although relations between the two Cold War allies have cooled in recent years.
