From AFP, via Yahoo! News:
China announced it would temporarily ease restrictions on foreign media ahead of the 2008 Olympics, allowing journalists to report more freely across the country, including in Tibet.
However, the new rules, which will take effect from January 1 next year, will expire in October 2008, after the Olympic Games are held.
Foreign journalists are currently only allowed to report from the cities where they are accredited and are required to seek approval from local governments where they want to report.
