The New Global Trade War: How Tariffs Are Reshaping Where the World Makes Everything

As Washington intensifies its campaign against Chinese imports, companies are redrawing supply chains across Asia, Mexico and beyond — creating a global manufacturing map increasingly shaped by tariffs rather than efficiency.

WASHINGTON — For decades, globalization followed a relatively simple formula: Companies manufactured products wherever labor, materials and transportation were cheapest, then shipped them to consumers around the world.

That calculation is rapidly changing.

A widening trade confrontation between the United States and China is forcing manufacturers to reconsider not only what they produce, but where they produce it. Tariffs, national-security concerns and increasingly complicated rules governing a product's country of origin are helping reshape a global supply chain built over generations.

The latest confrontation centers on what the Trump administration calls illegal "transshipment."

A White House report released this week accused exporters in more than 40 countries of participating in or being vulnerable to schemes that route Chinese products through third countries before they enter the United States. Goods can be relabeled or undergo limited processing before being presented as originating somewhere other than China, allowing importers to avoid higher American tariffs. The administration estimates such practices could be costing the federal government $19 billion to $26 billion annually in lost tariff revenue.

The countries identified as potential transshipment risks include some of America's largest trading partners and allies, including Mexico, Canada, India, Japan, South Korea, Vietnam and members of the European Union.

But behind the accusations lies a much larger transformation.

Since the first major U.S.-China tariff battles began in 2018, manufacturers have increasingly adopted a strategy sometimes called "China Plus One": maintaining operations in China while adding production elsewhere.

Vietnam, Mexico and India have emerged as important beneficiaries. Southeast Asia has experienced particularly strong growth in U.S.-bound trade; ASEAN shipments to the United States increased 29 percent in 2025.

Not all of that represents tariff evasion. In many cases, companies have made genuine investments in factories, workers and infrastructure outside China. Research by Rhodium Group found that previous tariff rounds contributed to durable new manufacturing capacity in countries including Vietnam, Mexico and India, even as transshipment also occurred.

China itself is adapting.

Chinese companies are increasingly investing overseas, effectively moving parts of their manufacturing networks closer to foreign customers. China's strength in electric vehicles, batteries, electronics and other advanced industries has made completely removing China from global supply chains extraordinarily difficult.

The result is something very different from the globalization of the 1990s and early 2000s.

Instead of choosing a factory location primarily because it offers the lowest production cost, multinational companies must increasingly consider tariffs, political alliances, national-security restrictions and whether future trade rules could suddenly make an existing factory uneconomical.

Washington is also preparing to police those supply chains more aggressively. The administration says U.S. Customs will use an artificial-intelligence system dubbed "Detective Border" to help identify suspicious trade patterns and determine whether products have been improperly routed through third countries.

That could make determining where something was truly "made" increasingly important — and increasingly complicated.

A smartphone might contain components manufactured in China, chips produced in Taiwan or South Korea, assembly performed in Vietnam and software developed in the United States. Under the emerging trade system, the journey of every component can affect what tariff is ultimately paid.

The new global trade war, therefore, is no longer simply about whether Americans buy products from China.

It is becoming a contest over where the world makes everything — and who gets to decide where "made" really means.
