Non-intervention in the internal or external affairs of other states，即不干涉内政原则。互不干涉内政，政治学术语，是一项国际法原则，从国家主权直接引申出来的，1954年由周恩来提出。Non-intervention即可指的（尤指对外国事务的）不干涉；不干涉（原则）。

内政就实质而言是国家在其管辖的领土上行使最高权力的表现。也就是说，凡是国家在宪法和法律中规定的事项，即本质上属于国家主权管辖的事项都是国家内政。如决定本国政治制度、经济体制、政权组织形式和国家政策、社会进步、文化教育体制以及建立对外关系、缔结条约、参加国际组织、出席国际会议、宣战等等都属国家内政。总之，内政包括一国主权范围内的任何措施和行动，包括政治、经济、社会、文化、外交等多个方面。
