By making it possible for literally at least one other country to do something the USA doesn't like without being destroyed.
It won't. What it will do is allow successful revolutions to have a large trade partner to help develop their country. But China isn't in the business of spreading revolution or defending allies like the USSR was. If Cuba got invaded by the US tomorrow I highly doubt China would do much more than try and coordinate with the UN to stop it or something. Perhaps they may secretly fund Cuba or whatever but again, I doubt anything directly. Not hating on China or anything. Its perfectly reasonable to look out for yourself first as a country. Even if it seems a bit, nationalist (because it is), its a reasonable approach.
Lead by example, with mutual benefit trade. Directly intervening in other countries is not the way, as harsh as it sounds.
But what about offering non-predatory loans and helping people develop?
