Indian politicians accused the scandal-plagued government of Prime Minister Manmohan Singh of floundering in fear before China.
"China realizes that India has a weak government, and a prime minister who is powerless," said Yashwant Sinha, a former foreign minister from the opposition Bharatiya Janata Party.
He demanded a stronger response. "A bully will back off the moment it realizes that it's dealing with a country which will not submit to its will," Sinha said.
Former Defense Minister Mulayam Singh Yadav called the government "cowardly and incompetent." He warned that China was trying to annex more territory to add to the spoils it took following its victory over India in a brief 1962 border war.
Defense Minister A.K. Antony countered that India is "united in its commitment to take every possible step to safeguard our interests."
Supporters of the right-wing Shiv Sena party burned effigies of Singh, Antony and other top officials Wednesday, demanding India retaliate by barring Chinese imports.
