Boycotts in Mexico banning the purchases or endorsement of American products have spread across the nation in response to the first few days of the Donald Trump administration. A Mexican food activist group urged consumers to cease buying U.S. products, while additional boycotts have called for Mexicans to ban U.S. companies Walmart, Starbucks and McDonalds and products like Coca-Cola.

Frustrations between the countries have surmounted since Trump signed an order last week greenlighting a U.S.-Mexico border wall just days into his presidency. The Trump administration also proposed a 20 percent tax on Mexican imports in a bid to get the country to pay for the wall, further straining relations. Mexican President Enrique Peña Nieto then canceled a scheduled meeting with Trump after repeatedly vowing that Mexico would not pay for the wall.

Starbucks was a major target of a boycott with social media hashtag reading “#AdiosStarbucks began to trend last week. A Mexican state governor also called for Mexicans to cease buying cars from U.S. car company Ford, Reuters reported.

“It’s time for Mexicans to show what we’re made of,” Alejandro Moreno, governor of the Mexican state Campeche, told reporters about the boycotts. “Actions like this should multiply across the country.”

Mexico could leave the North American Free Trade Agreement (NAFTA) if negations with the U.S. do not go well. Trump had said he would abandon the trade pact between Mexico, North America and Canada that went into effect in 1994. Mexico, on the other hand, could very well pursue its own tariffs on American product and lift restrictions on visas so more migrants could travel into the U.S., The Guardian reported.

“He ranted and raved during the campaign, but the guy has a knife to our throat now,” a political science professor at the Autonomous Technological Institute of Mexico, Federico Estévez, told the Guardian in response to Trump’s policies. “But it’s not like Mexico has no leverage. It does.”
