These are just squabbles. Trump as we know put the economy above all else, China are highly focused of "saving face " and propaganda. Its all just sabre rattling in my view .
The banning Wechat is a huge topic here in china and the hypocrisy is just laughable from the Chinese side. There will an agreement in which both side claim they won.
Its an interesting topic , I have had these frank discussions several times in my class with managers, most are CPC members. Their attitude is that if Western governments do too much whinging and no action (hows the punishment for China going on due to the Virus going? That will be forgotten). For example they say if Western governments want nothing to do with China why are they scrambling all over themselves to come here, like Microsoft, Amazon, Tessla, AMD, Dell, Apple etc. They fully admit the playing field is not level by any means but say their Chairmen is the leader of China not the USA, his duty is to the Chinese people not to the world.
They look at the facts and ignore the tantrums Also they are baffled by the twitter wars and peoples need to vent all the time. It just doesn't comprehend with them . The other aspect is that they play the long game, they know Trump will go at some point where as the CPC are in place for decades to come. Trump like any president can reply on quick and empty promises, bluster to win elections (last time it was the Wall, this time it will be 'lets get China' folks) , whereas they XijinPing (like Putin) is their for life
They are certainly no militay threat but they are taking over the world by stealth and economic policy (e.g. Africa) while USA and Europe get caught up in internal squabbles.
Well if China is in such a strong position and playing the "long" game, then why is banning WeChat a huge topic in China when Trump hasn't even banned it yet?
Oh well, only time will tell...
