Up to last week Britain was determined to go ahead with the Huawei deal, no matter what Trump thought - now he puts his foot down and the deal is gone.
Whatever the rights and wrongs of China, it has not changed - Trump is now calling the shots on Britain's economy

Up to last week some were determined to go ahead. There were already calls from within the Conservative Party to re-think the decision. The decision to go ahead with Huawei was taken before China decided that Britain no longer had any say/responsibility with regard to Hong Kong. I believe that it is the situation in Hong Kong/China (including with the Uighurs) that has caused a pause, and a re-think, not anything Trump has done/said.
