Besides this, India has also agreed to cut short the number of pilgrims' batches from 16 to 10 though official sources here maintained that the total number of pilgrims will not be reduced.
These developments are in addition to the postponement of the Yatra, a tourism attraction in the hill state, for 13 days. Originally, the Yatra was scheduled to begin on June 1.
When contacted, State Tourism Minister Prakash Pant confirmed that the Yatra would remain suspended for nearly 15 days during Olympics in Beijing but remain non-committal over further changes.
The sources said China is not ready to take any chance during the Olympics especially in the face of mounting international pressure on the issue of Tibet.
The new developments have put extra burden on the Kumaon Mandal Vikas Nigam (KMVN), the government nodal agency conducting the pilgrimage, with the sources here expressing concern that it would become an uphill task for the smooth conduct of Yatra.

For the time being, the district administration has not given any permission to the monks to proceed further, the sources said.
