Certainly if China were to head to war, it must harden it's heart many more times than Israel and even Russia. 1000s of bombs in a week will not achieve the shock needed to break lines, not even 10 000s like Russia could field.
China has the industry and economy, but the question is, are there enough people follow up on occupation and to press all the triggers? I'm betting a lot on the new generation of Chinese, the 0-30 yr olds who grew up unopposed, to react with extreme organized violence if they are obstructed. China will need this generation, because there is not enough room to keep growing peacefully.
Beijing has reached the low/middle end of Europe living standards without fighting directly or creating a solid network of states to feed it. But it is already the largest economy in the world and there's not much room to grow from there. The answer is clear, it's the enemy nations that have to take a hit to their living standards so China can keep going. I'm not just saying it out of selfishness (which is nothing wrong either, China should take back its historical spot as undisputed no1), I also believe that in the long term, a China led hegemony will protect the most amount of people from upcoming climate change and population crises. Because the alternative is having someone like Trump be in charge of deciding the fate for billions of Africans, Latin Americans and Indians...
