Chinese foreign ministry spokesman Zhao Lijian said that a joint EU-Japan statement that mentioned a territorial dispute between China and Japan was an attempt to smear China and interfere in its internal affairs.
The statement expressed concern over the situation surrounding the disputed East China Sea islets known as the Senkaku islands in Japan. China also claims the islands, which it calls Diaoyu.
China lodged stern representations over the statement, which was published on Thursday, Zhao told a news briefing.
