Trump doesn’t want Europe to use Huawei in their communications networks because the Chinese government could order them to spy. Huawei says that’s ridiculous and they would never be made to spy by anyone. Trump tries to tell Europe that it wouldn’t take much for China to twist Huawei’s arm to do their bidding. Huawei says they’ll sign a document saying they won’t spy. Europe says that sounds like a good enough safety measure. Trump shows Europe he can easily twist Google’s arm and make them do something completely outlandish that they’d never do on their own...so how can Europe expect China not to be able to do the same to Huawei.
Trump thinks they are being naive to the cold realities of the world and hopes this will wake them up. ...and no he doesn’t want them to use US systems either. He wants European companies to do it.
