New Delhi, Mar 17: The Chinese crackdown on protestors in Tibet created uproar in the Lok Sabha on Monday, with several parties barring the Left expressing concern over the "cultural genocide" in Lhasa.

Members of the BJP, BJD, Samajwadi Party and RJD wanted India to condemn the violence and seek immediate intervention by the United Nations and the main Opposition even walked out.

Responding to the concern by members, External Affairs Minister Pranab Mukherjee expressed distress over the "unsettled situation and violence" in Tibet and wanted the causes of trouble in the autonomous region of China to be resolved through dialogue and non-violent means.

He informed the House that the government had already issued a statement in this regard. Raising the issue in Zero Hour, BJP's V K Malhotra alleged that Tibetans were being "massacred" in Lhasa and China was trying to "culturally finish Tibet", even when the Dalai Lama is saying he wanted autonomy and not separation from China.

While Samajwadi Party's Ramjilal Suman wanted government to inform the House about its stand on the 'violation of human rights' in Tibet, BJP's Adityanath claimed if China was not stopped now, it would "annex Nepal and then the Northeastern states."

B Mahtab of the BJP wanted the government to protest the "ethnic cleansing and tell China to exercise restraint and stop cultural genocide."

He also asked the government to press for immediate UN intervention in Tibet. When the Opposition walked out, Mukherjee said the policy on Tibet and China, which was formulated in 1959, remained the same and no government, including NDA, had changed it.
