Arab Union
On May 28, 1958, the U.S. recognized the Arab Union that formed between Iraq and the Hashemite Kingdom of Jordan. U.S. recognition of the new state was accorded in an exchange of notes between the American Embassy at Baghdad and the Ministry of Foreign Affairs of the Arab Union. In announcing U.S. recognition, the Department of State noted that the Arab Union's constitution stipulated that "external affairs will remain as they are at the present time" with the two Kingdoms that had joined to form the new state. Consequently, formal diplomatic relations were not established between the U.S. and the Arab Union, and diplomatic relations continued uninterrupted between the U.S. and Iraq, and the U.S. and Jordan.
