China's?territory is not allowed "to be purchased" by anyone,?Spokesman Liu Weimin of Foreign Ministry made the remarks after Japanese Prime Minister Yoshihiko Noda admitted his gov't was negotiating with a "private owner" to "nationalize" part of the "Senkaku Islands" (China's Diaoyu Islands).

"The Chinese government will continue to take necessary measures to resolutely safeguard the sovereign rights of the Diaoyu Islands and adjacent islets," Liu said.

"The Diaoyu Islands and their adjacent islets have been inherent parts of Chinese territory since ancient times, and China has indisputable historical and jurisprudential evidence for this," said the spokesman.
