Donald Trump threatens intelligence block over Huawei: US diplomat

The US’ ambassador to Germany has said that President Donald Trump had threatened to cut off intelligence-sharing with countries that dealt with Chinese tech firm Huawei.

Washington has been pressing allies to ban Huawei, one of the world's largest tech firms, from next-generation 5G mobile data networks, saying it is a security risk.

Ambassador Richard Grenell said Trump "instructed me to make clear that any nation who chooses to use an untrustworthy 5G vendor will jeopardise our ability to share intelligence and information at the highest level." Grenell said on Twitter that the president had called him on Sunday from Air Force One, the presidential plane, to convey the message. Key US allies in Europe, notably Britain and France, have said they will not ban Huawei from building 5G networks but will impose restrictions. Publicly, the US has been restrained in its response, but Trump was reportedly furious with London.

US Secretary of State Mike Pompeo told the Munich Security Conference on Saturday that Huawei was a “Trojan horse for Chinese intelligence.” The tech company vehemently denies the US allegations, and Beijing has characterised its treatment as “economic bullying.”
