What was the border enforcement arrangement between President Trump and Mexico?

President Trump and Mexico's president established an arrangement where 25% tariffs on Mexican exports would be postponed in exchange for Mexico enhancing its border enforcement efforts. This deal specifically required Mexico to strengthen its actions against cartels and work to reduce the flow of illegal drugs into the United States. The arrangement represented a strategic use of economic leverage to achieve security goals along the shared border. By threatening tariffs but offering to delay them, Trump created incentives for Mexico to take more proactive measures in addressing issues that impact both nations.
