The renowned Chinese artist and dissident Ai Weiwei, held for 80 days without charge, was finally released under conditions that among other things forbid him to talk to the media. Ai has apologized to reporters, explaining that he is not allowed to talk about his case and, in fact, "I can't say anything."

But he went out of his way to pay tribute to Hong Kong, whose people had come out in great numbers to show their support for him after he was detained in April.

Ai risked official retribution by voicing respect and gratitude for people in Hong Kong, saying he was very moved by their actions.
