• Huawei is still prohibited from buying American parts and components to manufacture new products without license approvals.
• The U.S. Commerce Department said it will evaluate whether to extend the exemptions beyond 90 days.
The U.S. government has temporarily eased trade restrictions imposed last week on China's Huawei, a move aimed at minimizing disruption for its customers but dismissed by its founder who said the tech firm had prepared for U.S. action.
The U.S. Commerce Department will allow Huawei Technologies Co Ltd to purchase American-made goods in order to maintain existing networks and provide software updates to existing Huawei handsets.
The world's largest telecommunications equipment maker is still prohibited from buying American parts and components to manufacture new products without license approvals that likely will be denied.
The U.S. government said it imposed the restrictions because of Huawei's involvement in activities contrary to national security or foreign policy interests.
The new authorization is intended to give telecommunications operators that rely on Huawei equipment time to make other arrangements, U.S. Secretary of Commerce Wilbur Ross said in a statement on Monday.
"In short, this license will allow operations to continue for existing Huawei mobile phone users and rural broadband networks," Ross added.
The license, which is in effect until Aug. 19, suggests changes to Huawei's supply chain may have immediate, far-reaching and unintended consequences for its customers.
"The goal seems to be to prevent internet, computer and cell phone systems from crashing," said Washington lawyer Kevin Wolf, a former Commerce Department official. "This is not a capitulation. This is housekeeping."
Huawei founder Ren Zhengfei on Tuesday said the temporary reprieve move bore little meaning for the company as it had been making preparations for such a scenario.
"The U.S. government's actions at the moment underestimate our capabilities," Ren said in an interview with CCTV, according to a transcript published by the Chinese state broadcaster.
He said Huawei was at odds with the U.S. government, not U.S. firms, and that Huawei is capable of making the chips it buys from the United States though that does not mean it will stop buying American chips.
The U.S. Commerce Department said it will evaluate whether to extend the exemptions beyond 90 days.
On Thursday, the Commerce Department added Huawei and 68 entities to an export blacklist that makes it nearly impossible for the Chinese company to purchase goods made in the United States.
The government tied Huawei's addition to the "entity list" to a pending case accusing the company of engaging in bank fraud to obtain embargoed U.S. goods and services in Iran and move money out of the country via the international banking system. Huawei has pleaded not guilty.
Reuters reported Friday that the department was considering a temporary easing, citing a government spokeswoman.
The temporary license also allows disclosures of security vulnerabilities and for Huawei to engage in the development of standards for future 5G networks.
Reuters reported Sunday that Alphabet Inc's Google suspended business with Huawei that requires the transfer of hardware, software and technical services except those publicly available via open source licensing, citing a source familiar with the matter.
Google did not immediately respond to a request for comment on the new authorization.
Out of $70 billion Huawei spent buying components in 2018, some $11 billion went to U.S. firms including Qualcomm Inc, Intel Corp and Micron Technology Inc.
"I think this is a reality check," said Washington trade lawyer Douglas Jacobson. "It shows how pervasive Huawei goods and technology are around the globe and if the U.S. imposes restrictions, that has impacts."
Jacobson said the effort to keep existing networks operating appeared aimed at telecom providers in Europe and other countries where Huawei equipment is pervasive.
The move also could assist mobile service providers in thinly populated areas of the United States, such as Wyoming and eastern Oregon, that purchased network equipment from Huawei in recent years.
John Neuffer, the president of the Semiconductor Industry Association, which represents U.S. chipmakers and designers, said in a statement that the association wants the government to ease the restrictions further.
"We hope to work with the administration to broaden the scope of the license," he said, so that it advances U.S. security goals but does not undermine the industry's ability to compete globally and remain technology leaders.
A report on Monday on the potential impact of stringent export controls on technologies found that U.S. firms could lose up to $56.3 billion in export sales over five years.
The report, from the Information Technology & Innovation Foundation, said the missed opportunities threatened as many as 74,000 jobs.
Wolf, the former Commerce official, said the Huawei reprieve was similar to action taken by the department in July to prevent systems from crashing after the U.S. banned China's ZTE Corp , a smaller Huawei rival, from buying American-made components.
The U.S. trade ban on ZTE wreaked havoc at wireless carriers in Europe and South Asia, sources told Reuters at the time.
The ban on ZTE was lifted July 13 after the company struck an agreement with the Commerce Department that included a $1 billion fine plus $400 million in escrow and replacement of its board of directors and senior management. ZTE, which had ceased major operations as a result of the ban, then resumed business.
