In the wake of last Friday's incident when a group of Tibetan protestors stormed its Embassy, China is worried about the security of the Olympic torch that will go through India from April 17, sources said.

China is not even ruling out bypassing the country if it is not sure of foolproof protection, the sources said.

The Chinese Embassy has taken up the issue of security for the torch with the Indian government and the matter is under discussion, the sources said.

Top officials of the Embassy are engaged in talks with the authorities in the External Affairs Ministry and Indian Olympic Association about ensuring proper security for the torch, they said.

Asked about China's concern, National Security Advisor M K Narayanan said that the government will ‘make all arrangements to ensure that the Olympic flame passes through India safely’.
