US warship tracked after entering Chinese waters

The Chinese military has been monitoring a US guided-missile cruiser that illegally entered Chinese waters near the Nansha Islands on Tuesday morning, a spokesman from the People's Liberation Army said.

"Without the approval of the Chinese government, the guided-missile cruiser USS Chancellorsville illegally entered the waters near the islands and reefs of China's Nansha Islands on Tuesday," Senior Colonel Tian Junli, spokesman for the PLA Southern Theater Command, said in a statement.

"The theater command has organized naval and air forces to track, monitor and warn it off," he said.
