"In accordance with the newly announced changes to non-family travel to Cuba, OFAC [Treasury’s Office of Foreign Asset Control] is amending the regulations to remove the authorization for group people-to-people educational travel", the Treasury said in a press release.
Treasury also announced a ban on US exports of passenger and recreational boats as well as private and corporate aircraft to Cuba, the release said.
President Donald Trump has unravelled a series of Obama administration policies intended to normalise relations with Cuba and encourage increased US travel to the island.
In April, Trump overturned prohibitions imposed by the last three US presidents against lawsuits by American citizens seeking compensation for property seized by Cuba following the nation’s revolution 60 years ago.
