Cuba and the United States agreed on Monday to jointly prevent, contain and clean up oil and other toxic spills in the Gulf of Mexico, as they rush to conclude deals before President-elect Donald Trump takes office.

U.S. Charge d'Affaires Jeffrey DeLaurentis, upon signing the agreement, said it was one of a series of deals to protect the shared marine environment of the two neighboring countries separated by just 90 miles (145 km) of water.

Trump has threatened to scrap a still-fragile detente between the two countries unless Cuba makes further political and economic concessions.
