(Bloomberg) -- As if companies didn’t have enough to worry about, they now must contend with rising pressure from the U.S. on auto imports and the backlash of 5G telecommunications regulation.

In the latest salvos in widening trade hostilities, President Donald Trump gave European and Japanese car manufacturers six months to curb exports to the U.S. and bore down harder on China, barring sales from firms deemed a security risk and threatening to blacklist Huawei Technologies Co. from component purchases.

Companies around the world were already struggling against a tide of trade impediments and renewed doubts on the health of the economy. Chinese industrial output slowed more than economists had forecast in April, while U.S. production unexpectedly fell. Bundesbank President Jens Weidmann warned Thursday that the escalating trade dispute threatens to add “poison” to the world’s economy.

The U.S. trade stance “is adding a layer of complexity to corporates that’s proving very hard to read,’’ said David Page, senior economist at Axa Investment Managers in London. Companies “are finding planning over long-term horizons and business investment very difficult.’’

Trump will give the European Union and Japan 180 days to agree to a deal that would “limit or restrict” imports into the U.S. of automobiles and their parts in return for delaying new auto tariffs, according to a draft executive order seen by Bloomberg.

Security Threat

The administration has determined that imports of cars present a threat to national security by hurting domestic producers and their ability to invest in new technologies, the document shows. People familiar with the matter say Trump is expected to sign the order this week.

The timing couldn’t be worse: Carmakers already are dealing with slumping sales in China, the world’s biggest auto market, intensifying global competition and enormous outlays to develop electric vehicles and self-driving technology.

Jaguar Land Rover Automotive Plc’s China sales fell more than one-third in the nine months through December, and have continued to slide, the company said Wednesday. The Sino-U.S. trade war exacerbated the decline, said Chief Executive Officer Ralf Speth, adding that he hoped the “geopolitical issues between America and China can be resolved quickly.”

Koji Ikeya, chief financial officer of Mitsubishi Motors Corp. said on a conference call last week that trade friction between the U.S. and China, as well as between the U.S. and Europe, were among the main factors affecting the global auto industry.

In February, Toyota Motor Corp. President Akio Toyoda, in his capacity as chairman of the Japan Automobile Manufacturers Association, urged Trump to make a “careful and appropriate decision,’’ saying imported vehicles don’t threaten U.S. national security. Toyota has increased U.S. investment in response to the tariff threats, adding about $3 billion to a multiyear plan.

Consumer Impact

Ultimately, increased tariffs are bound to lead to higher prices for consumers.

At Walmart Inc., many products have escaped the stiffest levies so far, and first-quarter results were still strong. But the prospect of more tariffs on Chinese goods could hit them directly, leaving the company and other retailers with the choice between raising prices or sacrificing profitability.

“We will do everything we can to keep prices low, but increased tariffs lead to increased prices,” Chief Financial Officer Brett Biggs said in an interview Thursday. “It’s very item- and category-specific. There are some places where as we get tariffs, we will take prices up.” Shifting sourcing “is one of a number of actions that our merchants are considering.”

The comments echoed those of department-store chain Macy’s Inc.

“It is hard to do the math to find a path that gets you to a place where you don’t have a customer impact,” CEO Jeff Gennette said on an earnings call Wednesday, describing the impact of the U.S.-China trade negotiations as a “stay tuned” situation.

The telecom industry, too, faces a global threat. If Trump bans Huawei from purchasing essential components, the impact would be felt far beyond China’s largest technology company. It could depress the business of American chip manufacturers from Qualcomm Inc. to Micron Technology Inc., and potentially disrupt the rollout of 5G wireless networks around the world.

In Asia, shares of Huawei suppliers, including Sunny Optical Technology Group and AAC Technologies Holdings Inc., tanked on Thursday. But U.S.-based suppliers could take a hit, too: Huawei has said it devotes about one-third of its budget -- some $11 billion annually -- to the acquisition of American components. It counts 33 U.S. companies among its top 92 suppliers.
