From what i know , it is not easy at all to neither go to China, neither "defect" there, neither defect from authoritarian communist countries nearby. What you 'showed' me is people working in China, so controlled travel.

Based on what i know, i take your affirmation that it is easy to defect frop China either as ignorance, either as propaganda. If you have good info on the traveling part, please share so i and others can learn. On the original matter, i think it's not worth debating further if we do not share a same-ish perception of facts.
