4. United States and Vietnam
After a bloody war, the US and Vietnam normalized relations in 1995. Today, they collaborate on trade, education, and security, turning former conflict into a burgeoning partnership, bolstered by shared interests in regional stability. The U.S. and Vietnam have developed and sustained an active relationship on a range of humanitarian issues, particularly in achieving the fullest possible accounting of Americans missing and unaccounted for in Indochina (foia.state.gov).
