@Overbom bro Kerry had a hand and Meng release is a pre condition?
I think it mostly about seeing how they couldnt make China change its position.
You remember all the media fake news this year. All the aggressive rhetoric, all the talks with "allies and partners", making noises about trade sanctions etc.
Meanwhile China is now on a
mission crusade against US interests. Iran, Afghanistan, exporting inflation back to the US, climate etc.
To conclude, China has shown that whatever the US throws at it, it will withstand it without backing down. Meanwhile it occasionally throws a punch or two back at the US which cause serious disruption to it.
