To this end, China has created a vast Air Defense Identification Zone covering most of the East China Sea – including territories claimed and controlled by Japan and South Korea – where it has also declared disputed territories to be part of its own exclusive economic zone. These unilateral moves resemble the announcement by the United States in 1823 of what became known as the Monroe Doctrine, which, among other things, placed Latin America within a strictly US sphere of influence.
在这方面，中国建立了覆盖东海大部巨大的防空识别区，包括日本和韩国所主张和控制的地区；还宣布争议领土为其专属经济区的一部分。这些单方面行动和1823年美国所宣布的政策类似，美国的这一政策日后被称为门罗主义（Monroe Doctrine），门罗主义与其他一系列政策一起，让拉丁美洲成为美国的禁脔。
