Chinese diplomat Lijian Zhao alleged that US exaggerated security risks & placed groundless charges on Huawei. 'US crackdown is driven by concerns that Huawei's rise could pose a challenge to US technological hegemony, that US will not accept a Chinese company leading in 5G, not that Huawei really poses security risks', he tweeted. He added that 'US geopolitical mind-set decides that in order to kill Huawei, it would rather slow down 5G but EU does not want to delay 5G'. US has become more selfish. Campaign to kill Huawei has fully exposed US moral flaws, he said.
