Ambassador warns Washington not to 'drop rock on its own feet'

Responding to remarks by the US defense secretary about the Diaoyu Islands earlier this week, China's ambassador to the US warned Washington not to "lift the rock off Japan only to let it drop on its own feet".

Cui Tiankai's remarks on Tuesday came one day after Russia blasted Japan's hawkish stance on territorial issues while Shinzo Abe was on a state visit to Moscow, the first by a Japanese prime minister to Russia in a decade.
