It is widely recognized as the world's largest international organization.

The policy was implemented by the United States government, enunciated in a note of January 7, 1932, to the Empire of Japan and the Republic of China, of nonrecognition of international territorial changes imposed by force. The doctrine was an application of the principle of ex injuria jus non oritur. Since the entry into force of the UN Charter, international law scholars have argued that states are under a legal obligation not to recognize annexations as legitimate, but this view is controversial and not supported by consistent state practice.
