The Japanese government has criticized former Prime Minister Yukio Hatoyama's acknowledgment of a "territorial dispute" with China over islands in the East China Sea, with the defense minister going so far as to use the word "traitor."
On his four-day private visit to China, Hatoyama told reporters in Beijing on Wednesday, "The Japanese government says there are no territorial disputes (between the two countries). But if you look at history, there is a dispute."
The remarks contradict his own government's position of indisputable territorial sovereignty over the islands that it calls Senkaku and that China calls Diaoyu.
"If his (Hatoyama's) remarks have been politically used by China, I'm unhappy," Japanese Defense Minister Itsunori Onodera said on television Thursday. "At that moment, the word of 'traitor' arose in my mind."
Dangerous waters: Behind the islands dispute The day after his controversial remarks, Hatoyama, 66, and his wife visited the Nanjing Memorial, which is for the estimated 300,000 people killed in a 1937 massacre by Japanese forces.
