MEXICO CITY - Mexican President Claudia Sheinbaum said Tuesday that she will send a diplomatic note to the United States after a US envoy criticized her at a UN conference for holding a political rally Sunday in Mexico's capital.

The rally was meant to inform the public about the latest US-Mexico negotiations that led Washington to agree to pause some trade tariffs on Mexican goods.

"The truth is there is no reason why, at a United Nations event, he is offering his opinion on an event in Mexico," the president told her daily press conference.

US President Donald Trump has said the trade tariffs are designed to pressure Mexico into doing more to crack down on immigration and drug trafficking along the US-Mexico border.
