Its funny seeing some the reactions from those like
@Stierlitz to China hosting Blinken and other EU officials.
It's diplomacy, it's the protocol you adhere to as a responsible power. Like come on politics, as is life, might be a game where you often times have to take a bite out of a shit sandwich, but offering the US Secretary of State 30 minutes of your time before sending him on his way doesn't even count as one of those moments.
Keep in mind, the Soviet Union and the USA despite at times being on the verge of mutual nuclear annhilation always kept diplomatic channels open and had more interactions then, than the the US and China are having now. Politicians in the US who even suggest that perhaps diplomatic channels with China be kept open are being called traitors. This is not a reality that's ideal for anyone. Much like how those on the US side who think China is still the same failed state it was during WW2 and would fold easily are delusional, those who think the Xi should be more like Putin and put the entire nation on the countdown to zero hour are equally delusional.
Geopolitics is a delicate dance, just let them do their jobs. If a mere conversation is enough to trigger you, then I suggest taking a break from following geopolitics because there's bound to be more stuff down the line that'll give you a genuine heart attack.
