In mid-April, the Chinese coast guard carried out maritime management and exercised sovereignty over the South China Sea Iron Sand Reef. China's coast guard conducted patrols in the area and collected video evidence of relevant situations concerning the Philippines' illegal activities. Additionally, Chinese coast guard personnel hoisted the five-star red flag to assert China's sovereignty over the Iron Sand Reef. The move was a significant demonstration of China's determination to protect its territorial claims in the South China Sea. The incident has sparked concern among regional countries and the international community, with some viewing it as a challenge to the existing regional order. The Chinese government has maintained that its actions are necessary to protect its sovereignty and maritime rights, and that it will continue to take all necessary measures to safeguard its interests in the South China Sea.
