China 'closes Tibet to tourists' ahead of anniversary

China has closed Tibet to all foreign tourists until the end of July, say travel agents in the region.
The move is being seen as an attempt by Beijing to prevent unrest ahead of celebrations marking 90 years since the founding of the ruling Communist Party.
Tibet saw a wave of violent anti-China protests in 2008, on the anniversary of a failed uprising against Beijing.
Beijing blamed the unrest on followers of the Dalai Lama, who it said were seeking to separate Tibet from China.
All foreign tourists need special permits to visit the Tibetan region - which Beijing calls an autonomous region - but the authorities have periodically barred all access, citing safety or security concerns.
Travel agents said the latest ban had been issued at least as early as June this year and would run until the end of July.
One agent, who spoke anonymously, said had he hoped the ban would be eased in time for Tibetan Buddhist festivals in August, but that his company had now had to cancel trips.
"We don't know the reasons behind it. Perhaps it has to do with something political, he told Reuters.
"We are disappointed because we lost a lot of money. We just have to tell clients we are sorry."
Another travel agent, at a hotel in the Tibetan capital, Lhasa, said the ruling was connected to the 90th anniversary celebrations.
"Even with a tour group, foreigners cannot come," said the agent.
A Foreign Ministry spokesman told reporters he had "no understanding" of the ban, said Reuters.
Tibet is largely closed to foreign media, so reports are difficult to verify.
