"I agree that the Prime Minister should have gone to Tawang, especially after the Chinese made certain statements about Arunachal Pradesh....In order to send a signal to China that from this point the position is clear from the political level that Tawang is ours," Sibal said.
"But Prime Minister did visit Arunachal Pradesh but he didn't go to Tawang. The Defence Minister did but then he made sure that the press was not allowed to give too much publicity," he added.
Sibal questioned why India had been shy of asserting its rights.
"To my mind, this is an error. This is a serious error. I don't know why we are afraid to assert our rights and maybe unnecessarily create doubts in the minds of people about how confident we are about our claims on Arunachal Pradesh," Sibal said.
