> China bans all activists' commemorations and highly regulates online discussion of the incident, including censoring criticism. But it is marked annually by activists elsewhere in the world, particularly in Hong Kong and Taiwan. [Emphasis added.]
Hong Kong is part of China, albeit as a special administrative region. So does the ban not apply in HK? Or does it apply in theory, but in practice is not enforced? Or are HK-based activists just more willing to flout the ban?
