evidence: China’s sweeping claims of sovereignty over the sea—and the sea’s estimated 11 billion barrels of untapped oil and 190 trillion cubic feet of natural gas—have antagonized competing claimants Brunei, Indonesia, Malaysia, the Philippines, Taiwan, and Vietnam. As early as the 1970s, countries began to claim islands and various zones in the South China Sea, such as the Spratly Islands, which possess rich natural resources and fishing areas. The failure of Chinese and Southeast Asian leaders to resolve the disputes diplomatically could undermine international laws governing maritime disputes and encourage destabilizing arms buildups. [...] In recent years, satellite imagery has shown China’s increased efforts to reclaim land in the South China Sea by physically increasing the islands' size or creating new ones altogether. In addition to piling sand onto existing reefs, China has constructed ports, military installations, and airstrips—particularly in the Paracel and Spratly Islands, where it has twenty and seven outposts, respectively. China has militarized Woody Island by deploying fighter jets, cruise missiles, and a radar system.
