"The fact that we wish to take on a leading role in resolving this (North Korean) issue has already been understood at the summit with the United States and the Group of 20 summit meetings", Cho said on Monday.
The North and the South have been divided since Korea's liberation from the Japanese at the end of World War II.
China's foreign ministry welcomed Seoul's peace gesture, saying it hopes "the two sides will move in a positive direction to. break up the stalemate and to relaunch the dialogue and negotiations".
