Clearly upset over the anti-China protests by Tibetans in New Delhi, the government on Saturday asked them to observe law of the land and refrain from political and other activities that affect India's relations with "friendly" countries.

"Tibetan refugees are our guests in India. All those in India, whether Indian citizens or foreigners, are subject to the law of the land regarding the crossing of our borders, marches or demonstrations," External Affairs Ministry spokesman Navtej Sarna said.

"Like our guests, Tibetan refugees, while they are in India, are expected to refrain from political activities and those activities that affect our relations with other friendly countries," he said.

Though Sarna did not specify any incident, the comment came in the backdrop of Tibetan refugees' march from Dharamsala in Himachal Pradesh with the intention to cross over to Tibet, which was aborted by the police.

Tibetan refugees have also made at least two attempts to storm into the Chinese Embassy in New Delhi, which were thwarted and scores of protesters detained.
