Chinese Premier Li Keqiang is expected to visit Hokkaido after attending a trilateral summit in Tokyo with his Japanese and South Korean counterparts early next month, diplomatic sources said Saturday.

Li, who was reappointed to a second five-year term as China's head of government last month, may also deliver a speech at an event in the Japanese capital to mark the 40th anniversary of the signing of a friendship treaty between Beijing and Tokyo, the sources said.

In Hokkaido Li is scheduled to join a conference that local political leaders are to participate in, the sources added.
