I know they're ass kissing ahead of Macron's visit to Beijing, but let's not dismiss this out of hand.
All wars, unless it ends in extermination of one side ends in some sort of negotiated settlement, even if the settlement term is unconditional surrender representative from both side still has to come together in a time and location to sign a paper saying as such. Zelensky in recent days has asked Xi to go to Kiev which I highly doubt will happen. It seems equally unlikely for the whole thing to be negotiated and signed in Moscow or Beijing either.
Thus another country may have the honor of hosting this event. We have one past example already where it took place in Minsk but given Belarus is now a lot closer to Russia I doubt Minsk is acceptable anymore. Early in the war Ankara was used as the location and it could still be the case in the future, alternatively what if Xi suggests to everyone to do this in Paris?
Which ever place Xi picks is going to be a somebody in the multipolar world, and France may be hedging.
