The Cuban Interests Section and its counterpart, the United States Interests Section of the Embassy of Switzerland in Havana, Cuba
or USINT Havana (the State Department telegraphic address) are formally sections of the respective Embassies of Switzerland,
although they operate independently of the Swiss in virtually all but protocol respects.
The two countries do not have formal diplomatic relations, but their respective Interests Sections function
as de facto embassies.
