Mexican President Claudia Sheinbaum on Tuesday said Mexico will take action if an agreement with Washington regarding new tariffs is not reached by the August 1 deadline set by her U.S. counterpart Donald Trump.

Over the past 30 years, Florida tomato growers’ share of the U.S. tomato market has shrunk from 80% to 20%, as Mexico-grown tomatoes become more common on shelves, Arizona State University professor Tim Richards said.
