BEIJING, Oct. 2 (CGTN) -- China firmly opposes a US warship's entry into the waters around China's islands and reefs in the South China Sea, said Wu Qian, spokesperson from China's Ministry of National Defense on Tuesday.

According to Wu, a US guided missile destroyer arbitrarily entered waters around China's islands and reefs in the South China Sea on September 30.

A Chinese missile destroyer immediately conducted an identification and warning process to drive it away, said Wu.
