Huawei has launched a legal challenge to a decision by US regulators to classify it as a national security threat.
It comes after the US Federal Communications Commission put curbs on rural mobile providers using a $8.5bn government fund to buy Huawei equipment.
The firm said evidence that it was a threat to security “does not exist”. The move is the latest in a series of challenges between Huawei and the US. The company has asked the US Court of Appeal to overturn the decision.
Speaking at a news conference at Huawei’s headquarters in Shenzhen, the company’s chief legal officer, Song Liuping, said: “The US government has never presented real evidence to show that Huawei is a national security threat. That’s because this evidence does not exist.”
This is the second legal challenge this year by the company as it fights back against the Trump administration’s policies.
Huawei launched similar legal action in May, challenging a decision to ban US government agencies from buying its equipment.
The company has been drawn into the disputes against the backdrop of the bitter trade war between the world’s two biggest economies.
It has a leading role in the manufacturing and selling key technology for next-generation 5G telecoms infrastructure.
