‘Very unfair’: Trump threatens extra 5% tariff on Mexico over water disputeNEWS | 09 December 2025Donald Trump has threatened to impose an additional 5% tariff on Mexico if it do not immediately provide additional water to help US farmers, accusing the country of violating a treaty that outlines water-sharing between the neighbors.
Under the treaty, Mexico must send 1.75 million acre-feet of water to the US from the Rio Grande through a network of interconnected dams and reservoirs every five years.
In a post on Truth Social on Monday, Trump said that Mexico “owes” the US 800,000 acre-feet of water due to violations of the treaty over the past five years.
He demanded Mexico release 200,000 acre-feet of water before 31 December, and more “soon after”.
The lack of water was hurting crops and livestock in Texas, Trump said.
“As of now, Mexico is not responding, and it is very unfair to our U.S. Farmers who deserve this much needed water,” Trump added. “That is why I have authorized documentation to impose a 5% Tariff on Mexico if this water isn’t released, IMMEDIATELY.”
A spokesperson for Mexico’s economy ministry did not immediately respond to a request for comment.
In April, US agriculture secretary Brooke Rollins said that Mexico had agreed to increase its water shipments to Texas to help make up a shortfall under the 1944 treaty.
