Protestor in India for the inclusion of “Team Tibet” in the 2008 Beijing Olympics

UPDATE > 27 August 2007

A few days later (as soon as the situation became normal in Tibet) the permit issuing authority resumed issuing permits.

However, it seems the Chinese government will stop issuing permits and visas for Tibet from Nepal again soon for security purposes relating to the upcoming Olympic 2008 games.
