MEXICO CITY (Reuters) – Mexico’s foreign minister Luis Videgaray will travel to Washington on Tuesday after threats by U.S. President Donald Trump to scrap the North American Free Trade Agreement, although a foreign ministry source said the trip was pre-planned.

A source in the foreign ministry briefed on the trip said it was organized before Trump’s latest warnings that he would prefer to scrap NAFTA than negotiate.

A second round of talks to re-negotiate the 23-year-old agreement are due to start in Mexico on Sept. 1.
