According to the American Foreign Policy news site, the White House is planning to pull out of UNESCO in an attempt to save money and due to the United Nations body's anti-Israel bias.
She said the Department of State today notified United Nations Scientific and Cultural Organisation Director-General Irina Bokova of the USA decision to withdraw from the organisation and to seek to establish a permanent observer mission to UNESCO.
The Trump administration has been preparing for a likely withdrawal for months, and a decision was expected before the end of the year, according to U.S. officials.
Paris-based UNESCO, which began work in 1946, is known for designating World Heritage sites. "The decision", Haley claimed, "is an affront to history and further discredits an already highly questionable United Nations agency".
The UN Education Science and culture organization had strained its relations with United States, following UNESCO's acceptance of Palestine as a full member.
The magazine said the decision was aimed at saving money and to protest what the U.S believes is UNESCO's anti-Israel stance. During the meeting between French President Emmanuel Macron and US President Donald Trump on the sidelines of the 2017 session of the UN General Assembly, Tillerson stated that the White House is debating whether to pull out of the agency.
