Huawei's chairman said Tuesday that the United States has "no evidence" that its equipment to build next-generation 5G wireless networks could be used as a vehicle for Chinese spy operations.
In a keynote address at the mobile industry's biggest annual global event in Barcelona, Guo Ping reiterated his company's position that there are no "backdoors" in its technology that could allow Beijing to spy on countries.
"The US security accusation against our 5G has no evidence. Nothing. The irony is that the US Cloud Act allow their entities to access data across borders," he said at the Mobile World Congress.
"We don't do bad things. Let me say this as clear as possible. Huawei has not and we will never use backdoors and we will never allow anyone to do so in our equipment. We take this responsibility very seriously," he added.
US President Donald Trump's administration has in recent months ramped up efforts to block Huawei, the leader in 5G, by urging allies to avoid the Chinese powerhouse, claiming that national security interests are at stake.
Washington considers the matter urgent as countries around the world prepare to roll out fifth-generation or 5G networks that will bring near-instantaneous connectivity, vast data capacity and assist futuristic technologies such as self-driving cars.
Network operators seeking to quickly deploy the new wireless networks are in a bind as Huawei's 5G equipment is seen as being considerably more advanced than that of its rivals such as Sweden's Ericsson or Finland's Nokia.
