Вот некоторые цитаты из англоязычного интернета:
Tibet travel has been severely resitricted
It was announced today that all travel in Tibet has been severely restricted for the immediated future. Unless you are part of a tour more than 10 people you are not allowed to get a permit that will let you travel beyond Lhasa. This measure was done in response to the activists in Tibet that protested for a Free Tibet.
Not sure when these restrictions will be lifted.
TRAVEL RESTRICTIONS IN TIBET
PLEASE NOTE: Important Notice for Travelers to Tibet
Present situation of April 30, 2007
Until further notice when you travel to Tibet you can only visit the Lhasa area. This is due to the protest at Everest Base Camp last week by five westerners.
You may be able to take an organized group tour to Shigatse and other areas, but at the moment this is unlikely due to political reasons. At the moment there are many soldiers situated around Tibet turning back tour groups and making them going back to Lhasa. The rules keep changing daily.
