Chinese communications giant Huawei has launched a political blitz to shore up support against attempts to stop it providing equipment to Australia’s 5G mobile networks, warning every federal MP of higher prices for consumers if the ban goes ahead.

In a dramatic escalation of the dispute over Chinese technology, the company has assured MPs from across all major parties that it is willing to undergo “evaluation and testing” by security agencies to prove it can be trusted.

The move comes as federal parliament prepares to vote on two bills intended to curb foreign interference in Australia, heightening concerns over Chinese access to the heart of the new mobile networks.

Fairfax Media understands the national security committee of federal cabinet has not considered a formal proposal to block Huawei from bidding for the 5G projects but key agencies have similar concerns to those that saw the company barred from the national broadband network in 2012.
