The statement comes two days after Chinese ships collided during a confrontation with a Philippine government supply mission.

China's military released a statement Wednesday that the destroyer Higgins entered the South China Sea unlawfully, according to several reports.

The United States is disputing China’s claim that it chased away an American warship conducting a freedom of navigation operation near Scarborough Shoal on Wednesday. A U.S. guided-missile destroyer sailed near Scarborough Shoal two days after two Chinese ships collided near the disputed feature while chasing a Philippine Coast Guard vessel.

The Chinese military said on Wednesday it monitored and "drove away" a U.S. destroyer that sailed near the disputed Scarborough Shoal in the South China Sea, while the U.S. Navy said its action was in line with international law.
