The move by Trumps administration to target Huawei after Obama's "pivot to Asia" is a political move to protect Silicon Valley.
Unlike Europe, China protected it's nascent high-tech sector via a national firewall. This meant that it was able to nurture high tech rivals to silicon valleys dominance of the global high tech sector. For example, whilst there is no European competitor to Amazon, there is a Chinese competitor - Ali Baba. Given the success of China's strategy, it suggests that perhaps Europe should have invested in a similar firewall to protect its digital sovereignty rather than left it to laissez-faire, leaving it open to predatory USA capital.
