Um, I am not sure how I feel about this. Why would Xi support a two-state solution? Isn't it more justified to have a one-state solution and return all of the land to the Palestinians? Won't a two-state solution eventually lead us back to another genocide? This feels off. I did not expect Xi to make such a statement.
One of the Soviet Union's problems was over extension though. They put a lot of energy into external affairs at the expense of internal ones, with mixed results. On the one hand we got Cuba, and on the other we have raging fascism in Ukraine and Poland, and the soviet union was killed and gifted by capitalists. China has not achieved the same things abroad, but has done well for its citizens so far.
I think no one expects China to arm the 2n International Brigades nor to have a hand in supporting every single communist party on Earth. But from the overextension that the USSR suffered (which I will remind you that at the time of its dissolution included a full on, 10 year-long war in Afghanistan) to the absolute neutrality that China displays there is a long way, with both of them staying at opposite extremes of the same axis.
We have to ask ourselves if it would be so extremely disastrous for China to simply condemn the act of imperialism and colonialism that is the existance of the state of Israel as it is today, and leave it there. It's not like this statement will appease anyone, with Biden already calling Xi a dictator nonchalantly and with the same aggressive US military maneuvers as always still going on periodically in Taiwan. It wouldn't even be that outlandish to simply retreat recognition of Israel as a state, which they wouldn't be the first to do.
China's pursue of neutrality and refusal to interact with the broader worldwide communist and/or anti-imperialist movement is exhausting. I'm not even talking about active statements of external policy even: the USSR's "Progress Publishers" used to take every text on Marxism-Leninism they could get their hands on and export them translated to 50 languages, while in order to get a copy of "The Governance of China" in one of the few languages it exists in you could see people in back in r/GenZedong having to write a letter to their local Chinese embassy written in unicorn blood hoping that they would agree to hand them a copy of, at most, one of the three existing volumes.
That's fair.
