近来，中国与越南、菲律宾等国在南海岛屿问题上的纷争日趋激烈，2014年3月，菲律宾船只强行突破中方海警船执法行动，向坐滩仁爱礁的菲方军舰补给物资。6月16日，越南船只冲撞中方作业区达1547次，并多次强行冲闯中方981钻井平台警戒区。中国政府明确表示，南沙群岛自古以来就是中国的神圣领土，南海是中国的核心利益，中国对南沙群岛及其附近海域拥有无可争辩的主权，有关国家应尊重历史事实，停止无理纠缠。美国重返亚太，欲插手南海问题。4月26日美国与菲律宾签署《强化防务合作协议》强调共同应对一系列挑战，分析称矛头直指中国。对此，中国外交部指出，中美在亚太事务中有着广泛的共同利益，两国应该加强合作，同本地区的有关国家一道切实促进地区的和平稳定发展繁荣，这才是根本之道。中国坚持南海争议应由直接有关的主权国家通过友好协商和谈判、以和平方式解决。
