日本对华政策一贯受到日美同盟、美国对华政策及中美日关系互动的影响与制约。特朗普时期,日本政府对中国"一带一路"倡议采取有限合作姿态,通过首脑互访等推动中日关系改善,其对华政策的战略自主性增强、两面性凸显。拜登上台后则更为重视与盟国的关系,关注全球性问题并倾向于参加多边国际合作,强调美国民主价值观的引领作用,反对激烈的关税战与对华全面"脱钩"。日本的对外政策取向在更大程度上与拜登的政策主张相互重合,日美双方的信任与协调将有所增强,日本对华政策亦将与美联动。为此,日本将更加注重以日美同盟为基轴的对华制度制衡,或将加大对"中国威胁论"及涉港、涉疆等问题的炒作力度,为确保"产业链安全"而对华采取更为谨慎的态度。Japan’s policy on China has always been influenced and restrained by the Japan-US alliance,American China policy,and the interactions among China,the US and Japan.During the Trump administration,the Japanese government took a limited cooperative stance on China’s Belt and Road Initiative,promoted the improvement of China-Japan relations through exchange of visits by heads of state among others,and both strategic autonomy and two-sidedness grew in Japan’s policy on China.After Biden came into office,the US will attach greater importance to relations with its allies,be concerned with global issues and incline to rejoin multilateral international cooperation,while emphasizing the leading role of American democratic values,and opposing fierce tariff wars and full“decoupling”from China.As Japan’s foreign policy orientation overlaps more with Biden’s,mutual trust and coordination between Japan and the US will be strengthened,and Japan’s policy on China will also be linked with that of the United States.For this,Japan will attach more importance to institutional containment on China on the basis of its alliance with the United States or more vigorously hype up“China threat”and issues related with Hong Kong and Xinjiang among others,while adopting a more cautious attitude toward China to ensure the“safety of the industrial chain”.
