Could someone plz explain wtf is going on in China

[Ron Burgundy]

I know they have some weird concoction of communism and capitalism. But how does it work? Obv there isn't a whole lot of govt regulation for manufacturing.

The govt spends so much resources censoring the media and internets, but doesn't care if factories use lead paint or poisonous wheat gluten.

I also don't understand our foreign policy with them. I know we borrow a crapload of money from them, that's about it.

On a related note, why is our foreign policy with Cuba so much different? If free trade and economic prosperity is the key to defeating communism in China, why wouldn't that work in Cuba? Is it just because politicians won't risk pissing of all the Cubans in FL, because FL is such an important state in the elections?
