A collision between a Philippine ship and a Chinese vessel occurred on Monday near the Spratly Islands in the disputed South China Sea, according to Beijing's Coast Guard. Beijing claims nearly the entirety of the South China Sea, a vital waterway facilitating over $3 trillion in annual maritime trade which is subject to overlapping claims by several nations, including China, the Philippines, Vietnam, Indonesia, Malaysia, and Brunei.China deploys various boats to patrol the waters and has transformed several reefs into militarised artificial islands. A series of confrontations between Chinese and Philippine vessels have occurred in disputed areas. New Chinese coast guard rules took effect on Saturday, June 15, which reinforce a 2021 law granting its coastguard the authority to use deadly force against foreign vessels in contested waters.
