Mexico plans to deliver water to farmers in drought-stricken Texas, a day after President Donald Trump threatened tariffs and sanctions for not providing water from the Rio Grande River under a 1944 treaty.

President Trump has threatened to slap new tariffs on Mexico for failing to deliver water under a decades-old treaty. But climate change has decimated river flows.

Mexico will deliver more water to Texas as part of a border agreement, which will help farmers in the Rio Grande Valley.
