Foreign relations of the United States
The United States of America has formal diplomatic relations with most nations. This includes all United Nations members and observer states other than Bhutan, Iran and North Korea, and the UN observers of Palestine and the Holy See. The U.S. maintains close unofficial relations with Taiwan, and de facto recognizes it as an independent state. Additionally, the U.S. has diplomatic relations with Kosovo, a non-UN member state which the U.S. officially recognizes, and the European Union.
The United States federal statutes relating to foreign relations can be found in Title 22 of the United States Code. The United States has the second-most diplomatic posts of any state after the People's Republic of China.
