Asia sees Mexico as building Trump鈥檚 new wall

By Mihir Sharma
WHEN the Mexican Senate on Dec. 10 to approve a 50% tariff rate on a broad swathe of countries 鈥 China, India, Brazil, South Korea, Vietnam, and Taiwan among them 鈥 politicians from President Claudia Sheinbaum鈥檚 ruling Morena party pretended they did it for their own reasons. Nobody in Asia believes that this is a bold declaration of economic independence, however. It鈥檚 seen instead as opening a new and unexpected front in Donald Trump鈥檚 trade war on the world.
The vote waived the senators鈥 usual right to discuss amendments in committees, and it passed 76-5, with the opposition abstaining. Officials grandly delivered the usual lines that accompany measures cutting off trade: That they would protect local industry, that revenue would increase by , that there would be more money to spend on supporting the unemployed.
But the real reason is that Sheinbaum is spooked by the deadline, six months away now, for reviewing the US-Mexico-Canada Agreement (USMCA). The speed with which she pushed the legislation through and its timing are no coincidence: Trump earlier this month that he might let NAFTA鈥檚 successor expire, or 鈥渕aybe work out another deal鈥 that ensured the US wasn鈥檛 鈥渢aken advantage of.鈥 Nobody wants that can of worms reopened.
About 80% of Mexico鈥檚 cross its northern border, and more than 80% of those are tariff-free under USMCA. The country depends upon US markets for 30% or so of its output. Mexican politicians are clearly scared enough that even acts of economic self-harm, like 50% tariffs, seem worth trying.
For the countries affected by the new rates out of Mexico City, this is a sobering reminder that they have more than just the US president to deal with. Trade is a complicated, disaggregated affair, which is why we have multilateral arrangements like the World Trade Organization. For much of 2025, we could pretend that wasn鈥檛 the case, with everyone scrambling to conclude their own bilateral deal with the US. But Sheinbaum shows that the trade conflicts Trump has launched are a cascading war, not some controlled confrontation.
Some will be hit particularly hard. One of the few industries in India that has carved out a successful export niche for itself is auto components. New tariffs may render them uncompetitive inputs for the giant factories along the US border serving America鈥檚 insatiable appetite for cars.
But a significant proportion of Indian exports to Mexico aren鈥檛 about the US at all. It is consistently among the top three or four destinations in the world for , for example. These aren鈥檛 meant for Americans, but they鈥檝e been hit with tariffs anyway. Sheinbaum is paying Trump protection money, but she鈥檚 taking it from the pockets of Indian producers.
And from her own citizens, of course. Opposition lawmakers pointed out that official modelers had given up on trying to estimate the effects of such a drastic change to Mexican trade policy. Citigroup鈥檚 economists that this will keep domestic inflation above 4% next year. All the other downstream, predictable effects of tariffs will apply: loss of competitive advantage, factories that face supply crunches, retaliation in fields where you don鈥檛 expect it.
And what happens if Trump decides that he doesn鈥檛 care about such expensive professions of loyalty, and shuts down USMCA anyway? Mexico City will have to rebuild trade relations with the rest of the world from scratch, but capitals from Brasilia to Beijing may not be particularly warmly disposed at that point.
Many countries in Asia had hoped that America-first trade policy 鈥 even if disruptive 鈥 might end up forging a united front against Chinese dominance of manufacturing. Sheinbaum鈥檚 surrender shows us a different path. In this alternative world, some countries will quietly enact the US president鈥檚 policies for him. The others will, perhaps with China in the lead, find a multilateral path to isolate collaborators.
Countries across Asia and beyond now know that it isn鈥檛 just their relationship with the US that is threatened, but with multiple other nations as Trump tries to push everyone into his dream, high-tariff world. He has already the European Union, for example, to impose 100% tariffs on China and India. It is unlikely to agree. Some countries will raise high and unpredictable trade barriers against each other and the world, while the rest will seek security and prosperity by integrating faster and further. Sheinbaum may have picked the wrong side.
In his first term, Trump promised to have Mexico pay for his wall. In his second term, he has succeeded. So what if the wall is one of tariffs, and not bricks?
