China: An American military ship illegally entered our waters, we are on alert
China's military says it has driven away a US Navy ship that illegally entered waters near the Spratly Islands in the disputed South China Sea.
"The US military's actions seriously violated China's sovereignty and security," said Tian Junli, spokesman for the People's Liberation Army Command.
There is still no comment from the US Navy.
China's Southern Theater Command said on its WeChat social media account that Chinese troops will remain on high alert.
