China, which claims almost the entire South China Sea, has ongoing disputes with the Philippines, Malaysia, Indonesia, Brunei and Vietnam. In China’s “standard map”, a U-shaped line of some 700 nautical miles starts from Hainan province in southern China and goes through the exclusive economic zones of the five other countries. An international court in The Hague ruled in favour of the Philippines in 2016, saying that China’s “nine-dash line” has no legal basis. China has since drawn a “10-dash line” in its maps.
“This is preparation for something bigger,” Brawner said about China “spending money on reclaiming reefs”.
