I want to know the answer to the following question:
What was deemed unacceptable to North Koreans and the Chinese during POW negotiations?
All the background I'm provided with is that "The on-again, off-again armistice negotiations continued for two years, first at Kaesong, on the border between North and South Korea, and then at the neighbouring village of Panmunjom.". Is that enough to answer the question?
Answer: no
