Trump threatens Mexico with tariffs over water dispute

President Trump threatens Mexico with trade consequences over water treaty violations, sparking tensions between the two countries.

U.S. President Donald Trump threatened Mexico on Thursday (April 11, 2025) with "escalating consequences" on trade unless it provides more water to Texas under a contentious decades-old treaty.

"Mexico has been stealing the water from Texas Farmers" and "last year the only Sugar Mill in Texas closed" for lack of water, Mr. Trump posted to his Truth Social platform.

He claimed that Mexico was violating a 1944 pact under which the United States shares water from the Colorado River in exchange for flows from the Rio Grande, which forms part of the border between the two countries.

"We will keep escalating consequences, including TARIFFS and, maybe even SANCTIONS, until Mexico honors the Treaty," Mr. Mr. Trump wrote.

The current treaty cycle expires in October and Mexico owes the United States more than 1.55 billion cubic meters, according to the two countries' boundary and water commission.
