New York, May 16 (TIWN): In a fateful swipe at telecommunications giant Huawei, the Trump administration issued an executive order Wednesday apparently aimed at banning its equipment from U.S. networks and said it was subjecting the Chinese company to strict export controls.

Huawei would be the largest business ever subjected to the controls, a law enforcement measure that requires it to obtain U.S. government approval on purchases of American technology, said Kevin Wolf, who had been the assistant secretary of commerce for export administration in the Obama administration.

"It's going to have ripple effects through the entire global telecommunications network because Huawei affiliates all over the planet depend on U.S. content to function and if they can't get the widget or the part or the software update to keep functioning then those systems go down," he said.

Asked if that could include barring Google from selling its Android operating system, which Huawei uses on its handsets, Wolf said it would be premature to say until he's seen a published order from the Commerce Department's Bureau of Industry and Security to be sure of the scope.

The executive order declares a national economic emergency that empowers the government to ban the technology and services of "foreign adversaries" deemed to pose "unacceptable risks" to national security — including from cyberespionage and sabotage.

While it doesn't name specific countries or companies, it follows months of U.S. pressure on Huawei. It gives the Commerce Department 150 days to come up with regulations.

Washington and Beijing are locked in a trade war that partly reflects a struggle for global economic and technological dominance, and Wednesday's actions up the ante.

The export restriction is "a grave escalation with China that at minimum plunges the prospect of continued trade negotiations into doubt," said Eurasia Group analysts in a report.

"Unless handled carefully, this situation is likely to place U.S. and Chinese companies at new risk," the report said.

It appears the law invoked in Wednesday's executive order, the 1977 International Emergency Economic Powers Act, has never before been declared in a way that impacts an entire commercial sector. It has routinely been used to freeze the assets of designated terrorists and drug traffickers and impose embargoes on hostile former governments.

The order addresses U.S. government concerns that equipment from Chinese suppliers could pose an espionage threat to U.S. internet and telecommunications infrastructure. Huawei, the world's biggest supplier of network gear, has been deemed a danger in U.S. national security circles for the better part of a decade.

U.S. justice and intelligence officials say Chinese economic espionage and trade secret theft are rampant. They have presented no evidence, however, of any Huawei equipment in the U.S. or elsewhere being compromised by backdoors installed by the manufacturer to facilitate espionage by Beijing. Huawei vehemently denies involvement in Chinese spying.

Huawei said blocking it from doing business in the United States would hamper introduction of next-generation communications technology in which the company is a world leader.

"We are ready and willing to engage with the U.S. government and come up with effective measures to ensure product security," the company said in a statement.

The restrictions "will not make the U.S. more secure or stronger," the company said. It said the United States would be limited to "inferior yet more expensive alternatives," which would hurt companies and consumers.

A senior U.S. administration official, who briefed reports on condition of anonymity, said in a hastily arranged call that the order was "company and country agnostic" and would not be retroactive. Officials said "interim regulations" were expected before final rules were set but were vague on what that meant.

In a statement, Federal Communications Commission Chairman Ajit Pai called the executive order "a significant step toward securing America's networks."

"It signals to U.S. friends and allies how far Washington is willing to go to block Huawei," said Adam Segal, cybersecurity director at the Council on Foreign Relations. Many in Europe have resisted a fierce U.S. diplomatic campaign to institute a wholesale ban on the Chinese company's equipment in their next-generation 5G wireless networks.
