Huawei, the world's largest telecommunications equipment manufacturer, is fighting a US-led campaign to convince its US allies to shut down the company's 5G high-speed network technology.
The US government claims that Huawei's products could be exploited by Chinese intelligence services for espionage – an assertion that the company has repeatedly denied.
The US offensive against Huawei has strained relations between Washington and Beijing, and threatens to disrupt the deployment of 5G networks around the world.
"We need to protect our critical telecommunications infrastructure, and the United States calls on all security partners to be vigilant and to reject any business that compromises the integrity of our communications technology or our national security systems." Saturday, US Vice President Mike Pence said. the Munich conference on security.
"America does not represent the world"
Ren, 74, founded Huawei 32 years ago after serving in the Chinese army as an engineer and in the oil industry. Son of rural school teachers in the mountains of Guizhou Province, he built his business into a global giant with an annual business turnover of more than 100 billion dollars.
Ren, who retains the title of CEO, told the BBC that even if the US persuaded more countries to stop using Huawei, the company "could just reduce things a little".
"If the lights go out in the west, it will still shine," he said. "And if the North is dark, then there is always the South America does not represent the world."
Huawei and Meng deny the charges against them last month by US prosecutors.
Ren told the BBC that he opposed his daughter's request for extradition from the United States, saying it was "politically motivated".
"They may have thought that if they stopped her, Huawei would fall, but we did not fall," he said. "We continue to move forward."
"It's a close relationship in some respects and not so close to others," he said.
"Throughout his childhood, I was in the army, which means that every year I left for 11 months, spending a month with my family," he said. "Our relationship during her childhood and adolescence was not so strong."
Later, he fought for Huawei's survival and worked regularly 16 hours a day. He admitted that he was close to any of his three children, but that he feels indebted to them.
"We always trust the United Kingdom"
The Chinese government vigorously defended Huawei as he was under increasing pressure from the United States and demanded Meng's immediate release. Foreign Ministry spokeswoman Hua Chunying said on Monday that Pence's remarks in Munich were "hypocritical, immoral, unjust and intimidating".
Huawei is already largely excluded from the US telecom equipment market and Ren told the BBC that if the US government continues to oppose the company's investments, it would simply transfer more business UK.
"We will continue to invest in the UK," he said. "We are still confident in the UK and we hope the UK will give us even more confidence."
