Led by the automaker BYD, China has established itself as the main car supplier in Mexico. The US worries China could use Mexico as a “back door” to sidestep tariffs and gain footing in the US market.

Foreign investment would be an economic boost for Mexico. The company has claimed that a plant there would create about 10,000 jobs. A Tesla competitor, BYD markets its Dolphin Mini model in Mexico for about 398,800 pesos—about $21,300 dollars—a little more than half the price of the cheapest Tesla model.
