Tech giant Huawei said on Friday its revenue fell in the first half of 2022 but new ventures in autos and other industries helped to offset a decline in smartphone sales under US sanctions.

Revenue fell 5.9 percent from a year earlier to 301.6 billion yuan in the six months through June 30, according to the company, the biggest maker of network gear for phone and internet carriers. It gave no profit but said its profit margin was 5 percent, which would be about 15 billion yuan.

Huawei Technologies, China's first global tech brand, has struggled since then-US President Donald Trump blocked access to US processor chips and other technology in 2019. The company denies American accusations it is a security risk and might facilitate Chinese spying.

Huawei, headquartered in Shenzhen, has stepped up development of network technology for autos, hospitals, mines and manufacturing. It says that is now less vulnerable to US sanctions.

“While our device business was heavily impacted, our ICT infrastructure business maintained steady growth,” Ken Hu, one of three executives who take turns as chairman, said in a written statement.

The first-half sales decline was an improvement over a 14 percent drop reported for the first three months of the year. The profit margin was wider than the first quarter’s 4.3 percent.

Sales by Huawei’s device unit, which includes smartphones, fell 25.3 percent from a year earlier to 101.3 billion yuan. Sales of network equipment to telecom carriers and companies rose.

Huawei reported a 113.7 billion yuan profit last year but said revenue plunged 28.6 percent from 2020.

Its auto venture has played a role in five models released by three Chinese automakers. Huawei supplies components and software for navigation, dashboard displays, managing vehicle systems and other services. (AP)
