In August, Trump signed a bill that barred the US government itself from using equipment from Huawei and another Chinese provider, ZTE Corp.
He said the results of the telecoms supply chain review affecting Huawei's case would be announced soon and all network operators would need to comply by the decision.
Huawei is willing to sign no-spy agreements with governments, including Britain, the Chinese telecommunications company's chairman said on Tuesday as the United States pressures European countries to shun the firm over spying concerns.More news: Meghan Markle's Instagram Posted a Photo of Archie's Feet for Mother's Day
The statement comes after news leaked this month that Huawei equipment would be used in 5G networks in the United Kingdom, creating tension between it and the U.S. The leaks resulted in Theresa May firing her defense minister Gavin Williamson, despite Williamson denying leaking anything.
Liang wants to ensure everyone that Huawei does not act on behalf of the Chinese government, and respects the local laws and regulations of each country.
"Huawei and 5G network is extremely important", Stoltenberg told a London business conference.
Liang was backing up earlier comments made by Huawei's Western Europe VP Tim Watkins, who said: "Our founder, Mr Ren, has made it clear that he has never been asked to hand over any customer data or information and he has made it clear that if asked he would refuse and if it was attempted to be enforced he would shut the company down".More news: Donald Trump Jr. Agrees to Senate Committee Interview
He said Huawei had long cooperated with Britain's National Cyber Security Centre's oversight of its technology, and it had improved its software engineering capabilities to make them the equal of competitors.
"Despite the fact Huawei has its headquarters in China, we are actually a globally operating company", he said. "No spying, no backdoors", said Liang.
The U.S. says Chinese law compels Huawei to cooperate with Beijing's espionage agencies.
The British government is in the middle of a furious debate over whether to let Huawei roll out its next-generation mobile service.More news: Antoine Griezmann announces shock departure from Atlético Madrid
