Xi's speech was pretty clear, the world will need to make a choice between war and peaceful cooperation, and if they pick war, they won't win.

It's quite relieving to see, I have been a little worried that China will be willing to do anything to avoid WW3, including allowing the US to salami slice them into another century of humiliation, but it does seem like they are very clear now that they will respond to western threats and won't back down.

In the words of Malcolm X:

I go for Mao Zedong much more than Nehru because I think that Nehru brought his country up in a beggar's role...Though the West doesn't love China, the West respects China. Now, the West doesn’t respect India, but it loves India

the idea was to scare white people,

making a statement against fascism and for peace
