美日韩“三边安全机制”的动向及影响

Trends of US-Japan-ROK Trilateral Security Mechanism

拜登政府上台以来,通过强化美日与美韩同盟、管理日韩冲突、自下而上发展美日韩多层次合作机制、将日韩嵌入美国多重盟伴体系等方式,加速打造“三边安全机制”。美日韩在军事安全合作、经济安全勾连、外交立场协调等方面取得显著进展,这既符合拜登政府推行对华竞争的战略需要,也是美日韩对乌克兰危机、朝鲜军事活动的回应。“三边安全机制”恶化地区与国际安全局势,危害区域与全球治理,冲击中国发展的外部环境。三国安全合作还有进一步加强的空间,但也面临各国国内政治、相互对安全威胁的认知差异等问题的困扰。

Since the inauguration of the Biden administration,the US,Japan,and Republic of Korea(ROK)have made significant progress in cooperation in terms of military and economic security as well as coordination of their diplomatic policy stances,setting the stage for an emerging Trilateral Security Mechanism among the three countries.This not only serves the Biden administration's strategic demand for competition with China but also reflects the collective response by the US,Japan,and ROK to the escalating Ukraine crisis and heightened military activities by ROK.The Biden administration has facilitated the establishment of this security mechanism by strengthening bilateral alliances with Japan and ROK,managing disputes between the latter two countries,fostering multilateral collaboration with a bottom-up approach,and embedding Japan and ROK into US alliance network.While there remains momentum and room for further collaboration among the three countries in military and economic security,the Trilateral Security Mechanism faces constraints stemming from the domestic politics of the three countries and challenges intrinsic to the mechanism itself.The Trilateral Security Mechanism has impacted both regional and global security stability,bringing negative effects on the national security and external environment of China.
