Sorry, Ami, I just checked them now. My frame of reference was prisoners, and I should have realized that the reference was broad enough to go beyond POWs. I already knew about the sale of organs of condemned prisoners in China and how the organs were often removed from the prisoners before execution. I didn't see an element of experimentation there. Your China link referred to experimentation, but by exploitation of vulnerable Chinese, not as far as I could see, of prisoners specifically. There's no doubt that the Chinese have a long way to go in basic human rights. Whether the objects of medical experiments are actual prisoners or not in China, there's a lot of inhumanity and horror going on there. Not that it's any justification for the crimes of the Bush administration. Nor does it excuses Obama's lack of prosecution of torture (which BTW he is obligated by treaty to prosecute.) The fact is, Obama can't prosecute a single Chinese official for torture, but he can prosecute every fucking one of the American torturers, but will not.
The North Korean link was basically unproven accusations. I believe them because they sound true, although some are puzzling. WHY were the Korean prisoners told to eat poisoned cabbage leaves? Why were families put in gas chambers together? This was punishment with a little bonus (experimentation) on the side? I think North Korea probably does torture prisoners - - I base this on the lack of accountability, the rigid nature of the regime, the inhumanity of both sides in the Korean war and the fact that both of these are Asiatic countries where there is a long tradition of torture, particularly in China, from which the culture must have spread centuries ago.
