Dec 8 (Reuters) - President Donald Trump on Monday threatened to impose an additional 5% tariff on Mexico if it doesn't immediately provide additional water to help U.S. 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 U.S. from the Rio Grande through a network of interconnected dams and reservoirs every five years.
