The Chinese authorities sometimes suspend issuing Tibet Entry Permits to foreign nationals, and may also restrict travel to Tibetan Autonomous Prefectures in neighbouring Provinces by those who have already obtained a permit. These restrictions can happen at any time, but in particular during sensitive periods or major religious festivals - especially around February and March, coinciding with the Tibetan new year festival and the anniversary of certain uprisings in Tibet. Travellers to all Tibet areas should check with tour operators or travel agents and monitor this travel advice and other media for information about travel to Tibet.
Ongoing political and ethnic tensions can lead to unrest and violent protest in Tibet. While foreigners are not normally targeted during unrest, you should be alert to the possibility of being caught up in any unexpected demonstrations or outbreaks of violence. Security measures are tight around any large public gathering and unauthorised gatherings may be dispersed by force. There have been a large number of self-immolations since 2011, including in Tibetan areas outside of the Tibetan Autonomous Region itself. The Chinese authorities tend to react quickly to these incidents and will increase the security presence in the area. Avoid becoming involved in any protests or calls for Tibetan independence. Don’t film or photograph any such activities.
