Liberal Legend II draws my attention to the case of Yuan Weijing, detained at Beijing Airport and her passport revoked when she attempted to travel to the Philippines to collect a human rights award on behalf of her husband, Prisoner of Conscience, Chen Guangcheng. Had she committed a crime? Well, no, but that matters not to the One Party State that has embraced a capitalist economy (hooray) whilst retaining a communist political structure, with all the individual suppression that it entails.
If I were a more thoughtful and knowledgeable person I would ruminate here upon whether it is wise to engage with China in the hope that such engagement will lead to political reform. But I'm not, so I will leave it up to you as to whether we should.
It also turns out that my blog isn't available in China. You can check if yours is here.
