Huawei is a private company that is not controlled by the Chinese government and would refuse to hand over information to Beijing although no such request has been made, the firm's Vice President of Western Europe said on Tuesday.
Huawei is "willing to sign no-spy agreements with governments" including the United Kingdom, its chairman Liang Hua said.
The Commerce Department's move to put Huawei on its "Entity List" means USA companies will need a special license to sell products to the Chinese company.
The Federal Communications Commission (FCC) has acted to prevent China Mobile from providing telecom services in the United States and may block other Chinese companies from the American market on similar grounds.
So can it please be allowed to put 5G modems everywhere?
Mr Trump signed an executive order which accused foreign powers of targeting United States technology, and industrial espionage.
Reuters reported on May 14 that Trump was expected to take action on the long-awaited proposal this week.
The order, which will not name specific countries or companies, has been under consideration for more than a year but has repeatedly been delayed, the sources said, asking not to be named because the preparations remain confidential.
"The security and resilience of the [United Kingdom's] telecoms networks is of paramount importance, and we have strict controls for how Huawei equipment is now deployed in the United Kingdom", a British government spokesman said on Tuesday.
Though no countries are specifically named in the emergency declaration, both the Trump administration and Congress have repeatedly singled out China's telecom giants ZTE and Huawei as potential threats to the USA, in particular their development of 5G technology.
Trade talks between the US and China are teetering after Beijing reneged on tentative agreements, according to the president and American officials.
"Huawei and 5G network is extremely important", Stoltenberg told a London business conference.
In January, US prosecutors said Huawei had conspired to steal T-Mobile trade secrets, and also charged Huawei and its chief financial officer with bank and wire fraud on allegations that the company violated sanctions against Iran.
The FCC voted unanimously to deny China Mobile Ltd's bid to provide us telecommunications services last week and said it was reviewing similar prior approvals held by China Unicom and China Telecom Corp.
Huawei representatives argue that the type of security audits that should be routinely performed on crucial technology from any vendor could mitigate any hypothetical risk their equipment poses.
The issue has taken on new urgency as USA wireless carriers rollout 5G networks.
