McClathy newspapers' Beijing bureau chief Tim Johnson blogs about the state of press freedom in China. In terms of overall policy,
[China's] Foreign Ministry announced that press freedoms instituted this year for foreign reporters during the Olympics were being extended indefinitely.
Of course, Johnson also notes, it remains important for a foreign journalist to prepare to be detained for any reason, by a local village chief, factory owner, local police, etc.
Johnson also links to a BBC collection of foreign journalists' anecdotes from October 17, on the state of press freedom.
