Hong Kong (CNN Business) Huawei's founder is striking a defiant tone in the face of American attempts to curb the Chinese tech giant's international reach and prosecute his daughter.

"There's no way the US can crush us," Ren Zhengfei said in an interview with the BBC that aired Tuesday. "The world needs Huawei because we are more advanced."

Huawei, the world's largest telecommunications equipment maker, is battling a US-led campaign to persuade American allies to shut the company's technology out of super-fast 5G networks.

The US government argues Huawei's products could be exploited by Chinese intelligence services for spying — a claim the company has repeatedly denied.

US prosecutors have also indicted Huawei and its chief financial officer, Meng Wanzhou , on charges of bank fraud and sanctions evasion. Meng, one of Ren's two daughters, was arrested in Canada in December and faces possible extradition to the United States.

The US offensive against Huawei has strained relations between Washington and Beijing, and threatens to disrupt the rollout of 5G networks around the world.

"We must protect our critical telecom infrastructure, and America is calling on all our security partners to be vigilant and to reject any enterprise that would compromise the integrity of our communications technology or our national security systems," US Vice President Mike Pence said Saturday at the Munich Security Conference.

Ren Zhengfei has been CEO of Huawei since 1988, building it into the world's largest telecommunications equipment maker.

'America doesn't represent the world'

Ren, 74, founded Huawei 32 years ago after serving in the Chinese military as an engineer and working in the oil industry. The son of rural school teachers in the mountains of Guizhou province, he has built his company into a global behemoth with annual revenue of more than $100 billion.

Ren, who retains the title of CEO, told the BBC that even if the United States were to persuade more countries to stop using Huawei gear, the company "could just scale things down a bit."

"If the lights go out in the West, the East will still shine," he said. "And if the North goes dark, then there is still the South. America doesn't represent the world."

Analysts agree that Huawei's vast global business, which is strong in many emerging markets, could survive even if the US government persuades more of its allies to exclude the company's products from 5G networks. The company is widely seen as outpacing its major rivals in 5G technology , making it almost irreplaceable for some wireless carries.

That would almost certainly plunge Huawei into a crisis similar to the one suffered by its smaller Chinese rival, which was crippled for months by a similar ban last year.

Huawei and Meng both deny the charges brought against them last month by US prosecutors.

Ren told the BBC he objects to the US extradition request for his daughter, claiming it's "politically motivated."

"They may have thought if they arrested her Huawei will fall, but we didn't fall," he said. "We are still moving forward."

In comments to the media last month, Ren said he misses Meng very much but also gave an ambivalent description of their relationship.

"It's a close relationship in some aspects and not so close in others," he said.

"Throughout her childhood, I was in the military, which means that each year I was away for 11 months, spending one month with my family," he said. "Our connection during her childhood and adolescence was not that strong."

In later years, he said, he was fighting for the survival of Huawei, regularly working 16-hour days. He admitted that he is not close to any of his three children, but feels indebted to them.

'We still trust in the UK'

The Chinese government has vigorously defended Huawei as it has come under increasing US pressure and demanded the immediate release of Meng. Foreign Ministry spokeswoman Hua Chunying said Monday that Pence's comments in Munich were "hypocritical, immoral, unfair and bullying."

She reiterated Beijing's criticism that the US government is aiming "to crack down on Chinese companies' legitimate rights and interests, fabricating lies and intervening in economic activities by political means."

UK intelligence services have concluded that there are ways to limit the risks of using Huawei equipment to build 5G networks, according to a report by the Financial Times. The UK government, which is a member of a key intelligence-sharing alliance with the United States, said in response to the report that it expects to complete its security review of 5G network technology in the spring but that no decision has been reached yet.

Huawei is already largely shut out of the American telecommunications equipment market, and Ren told the BBC that if the US government continues to oppose investment from the company, it will simply move more business to the United Kingdom.

"We will continue to invest in the UK," he said. "We still trust in the UK, and we hope that the UK will trust us even more."
