China's ambassador to Japan on Wednesday urged Tokyo to resolve historical and territorial issues to improve bilateral ties, while declining to comment on the possibility of a much-anticipated summit on the sidelines of an international conference in Beijing in November.
Speaking at a lecture in Tokyo, Cheng Yonghua said the biggest obstacle standing in the way of warmer relations is Japan's handling of historical and territorial issues.
The central government needs to "get rid of (those) political hurdles promptly," Cheng said.
