BEIJING - China's Defence Ministry yesterday vowed to guard its territorial sovereignty as Beijing sent two patrol ships near a disputed group of islands in the East China Sea that have been bought by the Japanese government, the most serious escalation in the dispute to date. The strong statements out of China prompted Japanese Prime Minister Yoshihiko Noda to put Japan's Self-Defence Forces on alert to deal with any emergency, although no reference was made to China's warnings. The Chinese military's top newspaper, the People's Liberation Army Daily, reacted to the island purchase by accusing Japan of "playing with fire" and posing the "most blatant challenge to China's sovereignty since the end of World War II". Chinese Defence Ministry spokesman Geng Yansheng warned that more unspecified steps could follow.
