New Delhi, Jan. 13: India plans to break off business, transport and tourist links with Pakistan and isolate it from the rest of the world if it fails to help to investigate the Mumbai terrorist attacks, the country''s Home Minister Palaniappan Chidambaram has told the Times.

Chidambaram accused Pakistan of doing nothing to assist India bring to justice the perpetrators of the attacks.

Asked what Pakistan was doing to help with the investigation, in which India handed over a dossier of evidence to its neighbour last week, Chidambaram said: "Zero. What have they provided? Nothing."

The minister will brief David Miliband on the investigation''s progress when the British Foreign Secretary meets him in Delhi today.

"There are many, many links between India and Pakistan, and if Pakistan does not co-operate and does not help to bring the perpetrators to heel, those ties will become weaker and weaker and one day snap," he said.

"Why would we entertain Pakistani business people? Why would we entertain tourists in India? Why would we send tourists there?" Mr Chidambaram refused to discuss when such measures might be introduced, but said: "We need co-operation soon." (ANI)
