evidence: From 2013 to 2018, Beijing undertook major island-building projects on seven outposts and constructed military bases on them, improving China’s strategic position, installing missiles, building runways, and enhancing its A2/AD capabilities. China continues to put pressure on other Philippine and Vietnamese outposts in the Spratly Islands. Furthermore, China has annexed the seven outposts and the area within the nine-dash line as part of "Sansha County" of Hainan Province, even though the Spratly Islands are more than 700 miles south of Hainan Island. In recent years, China has sent its fishing fleet, backed by the CCG and PLAN, into Indonesia’s EEZ in the North Natuna Sea (just south of the SCS) and around Natuna Island. Jakarta responded by sending the Indonesian Navy, which caused the fishing fleet and CCG to retreat, but both inevitably returned. The fact that China is willing to challenge Indonesia in the farthest reaches of the nine-dash line indicates Beijing’s intentions to eventually control the entire sea.
