The founder of Chinese electronics giant Huawei said it doesn't need the U.S.to survive.
United Kingdom security chiefs have advised that the risk of using its technology in the new 5G network could be contained.
In his first global broadcast interview since his daughter arrest, Ren accused the United States of forcing other countries into the campaign against Huawei.
"There's no way the U.S. can crush us", he told BBC "The world cannot leave us because we are more advanced. Even if they (U.S.) persuade more countries not to use us temporarily, we can always scale things down a bit", he added.
But the UK's intelligence agencies have said that it was possible to limit the risks involved in using Huawei's technology to build its network.
Ren also noted that Huawei will not withdraw any investment from the European countries even if there is a potential threat to be banned - for example from the United Kingdom, where the government review of the Huawei is planned for March-April this year.
"We still trust in the United Kingdom, and we hope that the United Kingdom will trust us even more". "Because if the USA doesn't trust us, then we will shift our investment from the U.S.to the United Kingdom on an even bigger scale", Ken told the BBC. "Because if the USA doesn't trust us, then we will shift our investment from the United States to the UK on an even bigger scale", Ren told the BBC.
The U.S. Justice Department denied the charges were politically motivated.
"The US like to sanction others whenever there's an issue, they'll use such methods - we object to this."
"We object to this. But now that we've gone down this path, we'll let the courts settle it", Ren said.
Huawei, which is China's largest private company, has been under scrutiny for its links to the Chinese government - with the USA and others expressing concern its technology could be used by China's security services to spy.
"The Chinese government has already clearly said that it won't install any backdoors".
"We're not going to risk the disgust of our country and of our customers all over the world, because of something like this".
Commenting on the spying concerns, the Huawei founder reiterated that the company will "never undertake" any spying activities. "If we have any such actions, then I'll shut the company down", he said.
Is Huawei part of the Chinese state?
Mr Ren is right, the USA makes up only a fraction of his overall business. China, by contrast, has accused the governments of fabricating stories about Huawei.
But he explained that this was an old expired passport of Meng's and not because his family curried special favour with the government.
