The White House issued a statement on the 7th, noting that President Trump signed a presidential memorandum that day, instructing the United States to withdraw from 66 international organizations that "no longer serve American interests."
According to the memorandum released by the White House, these international organizations include 31 United Nations entities—such as the United Nations Alliance of Civilizations, the UN Human Settlements Programme, and the UN Economic Commission for Latin America and the Caribbean—as well as 35 non-UN organizations.
In the presidential memorandum, Trump stated that the operations of these organizations and entities run counter to U.S. national interests, security, economic prosperity, or sovereignty.
After returning to the White House in January last year, Trump had already announced the United States would withdraw from UNESCO, the World Health Organization, the United Nations Human Rights Council, and others.
