There is currently some discord amongst the foreign correspondents of Beijing:
The Chinese government has invited 26 foreign journalists to Lhåsa to check out the situation themselves. The problem has been caused by the invitation list: AP is on, but Reuters is not. The Wall Street Journal and USA Today are also confirmed to be on the list.
Furthermore, according to Danwei sources, the invited media have not agreed to pool their reporting and video, meaning that the left out newspapers and new agencies will have to rely on their competitors for second hand information, photos and video.
But the debate may be merely academic: sitting in Beijing with a mobile phone and a modem, anyone with sufficient curiosity probably has access to better information than any of the Potemkin nonsense that the junket journalists will probably see.
UPDATE: Tim Johnson, the Beijing bureau chief for McClatchy Newspapers — not on the junket — has published a letter from the Foreign Correspondents Club of Beijing to the government complaining about restricted access
Charles Hutzler, Beijing Bureau chief of Associated Press, has a report from the trip. Shai Oster of The Wall Street Journal has another report. Geoff Dyer of The Financial Times has a report here, and an audio podcast and image gallery here.
