On September Eighth, two replenishment ships and two coast guard vessels from the Philippines entered the adjacent waters of Ren'ai Reef in China's Nansha Islands without the permission of the Chinese government. The China Coast Guard strictly warned the Philippine vessels in accordance with the law, tracked and monitored the vessels all the way and effectively regulated them. China has indisputable sovereignty over the Nansha Islands, including the Ren'ai Reef, and its adjacent waters, and firmly opposes the illegal transportation of construction materials by the Philippines to the illegal grounded warship. The China Coast Guard will continue to carry out law enforcement activities in the sea areas under China's jurisdiction according to law.
