Nepal has beefed up security in sensitive areas in and around the capital to prevent any anti-China protests as Tibetan exiles prepare to mark the 55th anniversary of the failed uprising in Tibet.
The move comes in the wake of media reports that some Tibetans in Kathmandu planned to carry out self-immolations to protest against Chinese rule in Tibet.
"We have tightened security to stop any untoward activity by the Tibetan refugees here," said Kathmandu deputy superintendent of police Arjun Chand.
"Security personnel have been deployed in highly sensitive areas such as Chinese Embassy, Chinese Visa office, Bouddhanath Stupa and Swyambhu Stupa in Kathmandu," he said.
Nepal is home to more than 20,000 Tibetan refugees. Every year some 2,500 Tibetans cross the border on their way to meet their spiritual leader, the Dalai Lama, in Dharamshala in Himachal Pradesh, the headquarters of the Tibetan government-in-exile.
Last year, during the anniversary of the 1959 rebellion against Chinese rule in Tibet, there were three self-immolation incidents in Kathmandu and two dozen people were arrested on suspicion of fanning anti-China activities.
More than 120 Tibetans have set themselves on fire in recent years to protest against what they describe as stifling Chinese control over their religious, cultural and political freedoms.
