Chinese scientists landed on Sandy Cay, a disputed reef in the South China Sea, over the weekend, an action the Philippines condemned as a violation of its sovereignty. The Philippine coastguard reported observing Chinese personnel conducting "illegal activities" on the uninhabited sandbank, which has become a flashpoint due to recent encounters between Chinese and Philippine vessels. A Chinese-flagged research vessel, Xiang Yang Hong 33, was spotted near the reef escorted by two coastguard ships. The Philippines conducted a maritime domain awareness flight to address these unauthorized scientific research activities, which they stated contravene the UN Convention on the Law of the Sea. This incident occurs amid escalating tensions between China and the Philippines over contested areas in the South China Sea.
