China production still hard to copy

The Reuters profile starts inside a factory in Dongguan, the dense manufacturing belt north of Hong Kong where electronics firms can still do something few rivals can match: turn a design into a shippable product fast, at scale, and with most of the supply chain close enough to reach by truck. The company in the story, Agilian Technology, makes electronics for Western brands and gets more than half its revenue from the U.S. In 2025, after Donald Trump’s tariff escalation, those orders froze for months and customers pushed the company to move production out of China. By early 2026, Agilian had reached an awkward conclusion. It needed backup capacity elsewhere. It still needed China more. (usnews.com) That is the part tariff politics often misses. Moving final assembly is one thing. Rebuilding the web behind it is another. Agilian looked at Malaysia, India, and even the U.S. It found the same problem many importers have found for years: the overseas factory can be rented, but the surrounding ecosystem cannot. Components still come from China. Engineering support still sits in China. Tooling changes still happen faster in China. Labor abroad often costs more than executives expect once training, yield losses, and delays are counted. So the “China-plus” strategy became exactly that: plus, not instead. (uk.news.yahoo.com) The timing matters because 2025 looked, for a while, like the year the model might crack. China’s official manufacturing PMI contracted for much of last year, and April 2025 was the weakest reading since December 2023 after Trump’s “Liberation Day” tariffs hit. Then the pressure changed shape. Beijing responded with export controls on minerals and metals that U.S. firms also needed. Tariff rates came down from the worst levels. By March 2026, China’s official manufacturing PMI had climbed back to 50.4, its strongest reading in a year. The shock did not disappear. It got absorbed. (usnews.com) Trade data tells the same story in bigger numbers. China’s trade surplus in January and February 2026 reached $213.6 billion, up from $169.21 billion a year earlier. In 2025, the country’s annual trade surplus rose about a fifth to a record roughly $1.2 trillion, even as exports to the U.S. fell sharply. That is not evidence that tariffs did nothing. It is evidence that Chinese manufacturing rerouted. Supply chains stretched through Southeast Asia, Latin America, and other markets. The factory floor kept humming because demand did not vanish. It moved. (thejakartapost.com) That persistence matters far from Dongguan. Southern California’s port complex lives on the fact that a huge share of U.S. imports still crosses the Pacific. If China remains the hardest place to replace for a broad range of electronics and consumer goods, then Los Angeles and Long Beach remain hard to displace as the main intake valves. The Port of Los Angeles handled 10.2 million TEUs in 2025, its third-best year ever. Long Beach had its busiest year on record at about 9.9 million TEUs. Some of that volume was front-loading ahead of tariff deadlines. But front-loading only works if companies still expect to source from Asia in the first place. (container-news.com) So the lesson from this one factory is not that diversification failed. It is that diversification has a ceiling when the original production base still does too many things at once. Import-dependent occupiers can add Malaysia, India, or Mexico to the map. They can spread risk across several plants. They can ask for optionality in leases and inventory strategy. But many will still want fast access to LA and Long Beach because the boxes are still coming from the same side of the ocean, packed with goods whose most irreplaceable parts were still made in southern China. Inside Agilian’s network, even the overseas lines depended on tariffed Chinese components.
