China wants a clear apology from Japan over its wartime aggression in China and clarification of its stance toward Taiwan put into a joint statement to be issued when President Jiang Zemin visits Japan later this month, Chinese Ambassador to Japan Chen Jiang said Wednesday.

At the Japan National Press Club, Chen said Jiang's visit -- which is the first by a Chinese head of state and considered pivotal to future Chinese-Japanese relations -- will give Japan a good opportunity to actually make a clear-cut expression of its attitude toward the past.

"The two sides should remove obstacles in expanding bilateral relations," Chen said.
