Chinese Vice Foreign Minister Liu Zhenmin on Sunday criticized the intrusion of U.S. warship which sailed within 12 nautical miles of a Chinese reef in the South China Sea as a "political provocation" in the name of "freedom of navigation."
The true purpose of the U.S. intrusion is to test how China will react to this kind of provocations, Liu said at a press briefing on the sidelines of the 27th ASEAN Summit and Related Summits.[Special coverage]
