As I just tweeted before about my fellow jury member, from China, who prohibited from leaving the country to attend the event in Berlin, to get to know about this case, here is the official release from Deutsche Welle:
Local authorities prevent the participation of a prominent Chinese citizen journalist in the international weblog awards, The BOBs, in Berlin
Chinese authorities are preventing Chinese blogger and citizen journalist Shuguang Zhou from leaving for Germany without providing any official justification. Zhou, who blogs under the name Zola, was invited by Deutsche Welle to be part of the international jury for the fifth annual weblog awards, The BOBs, and decide the winners. The jury will meet on November 26 in Berlin. On Thursday, November 27, he was supposed to announce the jury’s selection at a public event in the Communication Museum in Berlin.
According to information provided to Deutsche Welle, Zhou was stopped and detained by the police on Friday, November 21, on the border between Shenzhen and Hong Kong. On Monday, November 24, the police in Changsha confirmed that it Zhou wouldn’t be allowed to leave the country – as previously stated by the security officials. According to Zhou, the local authorities gave the verbal justification that he was a “possible danger to national security”. Deutsche Welle and the German Federal Foreign Office are in contact with the Chinese authorities to arrange Zhou’s departure – but as of Tuesday afternoon were still unsuccessful. Zhou plans to take part in the selection process online, as long as there is no interference.
