There's a fascinating interview with a former American PoW who was teaching in China when he was charged with espionage. He talks about his treatment and the methods they used to try and de-program the PoWs from years of pro-capitalist/imperialist propaganda. Sadly, I can't seem to find it now, but it was originally a radio interview if I'm remembering correctly and was re-published by either revolutionary left radio or guerrilla history.

I'd love to give it another listen of anyone knows where to find it.
