Ties between the United States and Mexico have deepened over 30 years of free trade, creating both benefits and irritants.

President Donald Trump and his press secretary said Friday that tariffs on Canada, Mexico and China will come on Saturday, with Trump stating that there’s no way those countries can avoid the levies.

Americans rely heavily on their bordering countries for everyday grocery items. President Trump’s plan to impose a 25% tariff on Mexican and Canadian goods could drive up food prices for the average shopper.
