WASHINGTON (AP) — Tourists from Chattanooga check into beach resorts in Cancun. Canadian auto parts feed factories in the American Midwest – and vice versa. Happy hour revelers raise glasses of Mexican tequila and mezcal at bars in Seattle.It adds up. The United States trades $1.9 trillion a year — $5 billion a day — worth of goods and services with its neighbors, Canada and Mexico. They have supplanted China to become America’s top two trading partners. So the stakes are high when it comes to fiddling with the rules that govern trade between the three countries. And after a year of President Donald Trump’s chaotic tariff policies, many U.S., Canadian and Mexican businesses would welcome the return of stability across North America.They are not likely to get it.The regional trade pact — the U.S.-Mexico-Canada Agreement or USMCA — that Trump negotiated and boasted about in his first term comes up for renewal Wednesday, a process that is likely to last months, maybe longer.

And the path forward is lined with landmines.“There’s going to be a lot of drama this summer,” Diego Marroquín Bitar, a fellow in the America’s program at the Center for Strategic and International Studies, said last week at a USMCA forum sponsored by the Cato Institute.
