Telecoms equipment giant Huawei has hit back at mounting US pressure, claiming American calls for allies to block its technology from the rollout of 5G telecom networks will have minimal impact on its global business.

Speaking with journalists at the company's headquarters in Shenzhen, Eric Xu, one of Huawei's three rotating chairmen, accused Washington of launching a "coordinated geopolitical campaign" against the company in order to gain leverage in a trade war.

But he played down the importance of bans on Huawei's 5G technology by Australia and New Zealand, two members of the so-called "Five Eyes" group of intelligence-sharing nations that also include the US, the UK and Canada.

"We certainly don't expect our 5G equipment to be chosen by all countries," Mr Xu said.
