China is making automakers around the world nervous. Its domestic carmakers—helped by generous state subsidies—are churning out alarmingly inexpensive electric vehicles at a relentless pace, saturating their home market and threatening EV manufacturers overseas.

But they might be getting carried away, a high-ranking Chinese official suggested on Friday.

Xin Guobin, vice-minister of industry and information technology, said that Beijing would take “forceful measures” to address what he called “blind” construction of new EV projects—i.e., not justified by demand—by some Chinese carmakers and local authorities, as reported by the Financial Times.

His comments come amid pressure from Europe in particular over a flood of low-priced Chinese EVs hitting its markets.

“Their price is kept artificially low by huge state subsidies. This is distorting our market,” European Commission President Ursula von der Leyen said in September. “And as we do not accept this distortion from the inside in our market, we do not accept this from the outside.”

To be sure, it’s more the threat posed by Chinese EVs in the long run than the current reality that has EU officials concerned. In Germany, the center of EU automaking, Chinese EVs still have just a small sliver of market share. But it’s growing fast, and that has many in Europe’s automotive powerhouse worried amid fresh economic woes, even as German carmakers—who do brisk business in China—have warned against tariffs on Chinese EVs for fear of retaliation by Beijing.

EU probes Chinese subsidies

In the weeks ahead, EU investigators will visit Chinese EV makers BYD, Geely, and SAIC as part of a probe into whether they have an unfair advantage thanks to government subsidies. Their visits—part of an EU probe announced in September and set to run for 13 months—will help determine whether the EU imposes higher tariffs to protect European carmakers.

Of course, more than subsidies are at play. “The Chinese car companies are extremely competitive,” Tesla CEO Elon Musk said at the New York Times Dealbook conference last year. “China is super good at manufacturing, and the work ethic is incredible.”

Musk suggested that Chinese companies will emerge as dominant players in the global automotive industry—a sharp departure from when he laughed about the quality of BYD cars in 2011.

Chinese EV makers also have supply-chain efficiencies that are tough to beat. BYD, for instance, keeps its costs low partly by owning the entire supply chain of its EV batteries, significant since a battery accounts for roughly 40% of an electric vehicle’s price. Backed by Warren Buffett’s Berkshire Hathaway, the Chinese carmaker recently overtook Tesla in global sales of electric vehicles.

Whereas Chinese EV makers face 27.5% tariffs in the U.S., in the EU that's just 10%. That’s encouraged them to target Europe as their home market gets increasingly crowded, although they’re also expanding quickly elsewhere, including in Southeast Asia and Latin America.

Last year, an Allianz Trade report stated that China’s EV makers pose a significant threat to European carmakers, particularly the “automotive-dependent economies of Germany, Slovakia and Czech Republic.” It called for higher tariffs on Chinese EVs, estimating that by 2030 they could cost Europe’s carmakers 7 billion euros per year in lost profits.

In the EU, Chinese-made EVs typically sell for 20% less than those made in the bloc, and their share of the EV market, which has grown to 8%, could reach 15% by 2025, according to Reuters.

The coming wave of Chinese EVs in America

Last year in China, BYD launched the Seagull, an EV with a cutthroat price of about $11,000. It quickly became one of the best-selling EVs in China. The Seagull and similar models from China could prove to be a disruptive force in overseas markets.

Chinese EVs might also become a common sight on American roads, eventually.

“No one can match BYD on price. Period,” Michael Dunne, CEO of Asia-focused car consultancy Dunne Insights, told the Financial Times earlier this month. “Boardrooms in America, Europe, Korea, and Japan are in a state of shock.”

Made-in-China EVs are sold in more than 100 countries, and the U.S. is the only market where they “have not yet really begun a big assault,” ZoZo Go CEO Michael Dunne, whose advisory firm specializes in the Chinese EV industry, told the Wall Street Journal.

Chinese EV makers are now searching for manufacturing sites in Mexico, which has a free trade agreement with the U.S. and Canada and could serve as a backdoor to those markets, a scenario American lawmakers have warned about.

Meanwhile, U.S. automakers have largely scaled back their EV ambitions—after making large initial investments—as demand has not been as great as anticipated. In a sign of the times, perhaps, all four of America’s largest carmakers passed on running Super Bowl ads this year—the first time that’s happened in 23 years.

But the threat from China has industry leaders on edge. Last summer, Ford executive chairman Bill Ford Jr. warned that American automakers are “not quite yet ready” to compete with Chinese rivals on EVs. “They developed very quickly, and they’ve developed them in large scale, and now they are exporting,” he told CNN. “They are not here, but they will come here we think at some point and we need to be ready.”
