「南海爭端」起因於南中國海週邊的幾個國家因為對於該海域的主權歸屬、海域劃分和相關海洋權利的重疊從而發生的衝突。由於南海地緣戰略、經濟利益高,中共乃以維護主權為由,積極採取維權措施。然由於中共此舉,影響南海週邊主權聲索國的權益至鉅,各國紛紛採取維權舉措,驟使南海區域安全憑添變數。中共近年來在南海地區填海造陸,從事提升軍事現代化作為,大幅提升了他的戰略縱深與在南海地區的戰力。中共乃以維護「核心利益」為由,陸續實施填礁造島工程,並大幅提升在南海地區的兵力投射能力,以及海洋執法力量等諸般作為。未來南海形勢能否繼續維持穩定,不僅取決於區域內國家能否有效增進互信、管控分歧、擴大合作,同時也會受制於美、日等域外國家南海政策和作為的影響,目前區域外國家也都因各自不同的利益以及政治利益考量,配合美國「印太戰略」介入了南海糾紛中,更為整個局勢增添了許多變數。
The "South China Sea Disputes" stem from the conflicts between countries bordering directly on the sea on the issues of their sovereignties, maritime boundaries, and overlaps of maritime rights. Due to the geostrategic value and high economic potential of the South China Sea, the PRC has taken aggressive measures to maintain and protect its sovereignty and rights in the region, which could profoundly influence the geopolitical and economic interests of other countries surrounding the region. In response, these countries have been taking increasing actions and promote their sovereignty claims, adding uncertainties to the security and stability around the South China Sea. In recent years, the PRC has made tremendous efforts on its land reclamation in the South China Sea and the modernization of its military. The completion of both projects can be helpful for its defense-in-depth strategy and enhance its military capabilities in the South China Sea. For the PRC's "core interests", it will continue to complete more land reclamation, strengthen its military forces, and improve its maritime law enforcements in the region. In the future, whether the South China Sea can move into stability or not depends on how the bordering countries build trust with each other, resolve their differences, and increase cooperation. Meanwhile, some non-claimant countries, such as the United States and Japan, try to involve in the maritime territorial disputes for their political considerations or national interests, making the situation more uncertain.
