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.
Honestly not even mad, this is completely expected lol
My guess is that as soon as he heard it, Xi leaned over to his aide and whispered "Looks like I owe you a beer" into their ear.
