蒙古欲加入联合国,蒋介石动用否决权予以否决;但第二次在美国压力下终未敢再次行使否决权1955年12月,苏联提出蒙古人民共和国加入联合国的申请提议。因台湾国民党当局尚据安理会常任理事国之席位,故动用否决权将之一票否决。其实,《联合国宪章》本无“否决权”之 When Mongolia wanted to join the United Nations, Chiang Kai-shek used its veto power to reject it; but for the second time, he did not dare to exercise the veto again under the pressure of the United States. In December 1955, the Soviet Union proposed the Mongolian People’s Republic’s application for membership in the United Nations. Because Taiwan’s Kuomintang authorities still hold seats in the Security Council as permanent members, they will be vetoed by one vote. In fact, there is no “veto” in the “UN Charter.”
