联合国的英语名称为 UnitedNations,它的成员往往被称为“成员国”,也就是说,只有拥有政治外交主权的国家才能成为联合国的成员,如中国的台湾、香港就不能成为联合国的成员。而世贸组织则不同,其英文名称为World Trade Organization,其成员被称为 Member,而决不称国家(如Country、nation 或 state),它并不要求它的参加者是主权国家。事实上,中国香港早已是 WTO 的正式成员。 The UN’s English name is UnitedNations. Its members are often referred to as “member states.” That is, only countries with political and diplomatic sovereignty can become members of the United Nations. For example, in Taiwan of China, Hong Kong can not become a member of the United Nations. The WTO is different, its English name is World Trade Organization, its members are called Member, and never called a country (such as Country, nation or state), it does not require its participants are sovereign states. In fact, Hong Kong, China, has long been a full member of the WTO.
