The original I read had such helpful statements as ‘the chinese government insisted that every outside researcher was accompanies by a chinese partner’, ‘the government took days to procure the data, and when they finally did, a lot was missing’ and ‘a visit to x was denied for unclear reasons’.
I’m sorry, I’m vaguely remembering these, so they may not be 100% accurate.
Then the western researchers made one gloriously ambiguous statement while still in China, and turned about after they left the country.
