I'm sure Xi is beyond having his feelings hurt by Biden, but just look at Bilken's reaction lmao.
Inviting a head of state to your country to publicly insult them is unacceptable anywhere, so this is only going to further tarnish the shitty reputation of American diplomacy.
I mean, isn't the danger part of the point? If it's very risky to do stupid shit like playing "i'm not touching you" with chinese waters because you can't just call the chinese and say "hey this extremely threatening thing we're doing is just for kicks, don't worry", you're less likely to play dangerous games. Forcing the duplicitous Americans to show their cards publicly for any communications is the best deterrent.
