NEW DELHI -- India Saturday renewed demands that Pakistan curb "terrorism" and warned good relations would depend on concrete steps taken by Islamabad to stem cross-border militancy on Indian soil, AFP reported.

The comments came less than a day after U.S. Secretary of State Colin Powell wound up a peace mission to the troubled region where nuclear powers India and Pakistan have massed almost a million troops on their borders.

Before leaving India Friday, Powell said: "I leave here very encouraged that we can find a solution to this troubling situation."

Home Minister Lal Krishna Advani, the de facto number two in the Indian government, said last week's address by Pakistani President Pervez Musharraf, in which he promised to crack down on militants, meant little to India.

He repeated his view that the speech was "important and path-breaking" but he told a seminar of Islamic academics: "Mere speech is not enough. We have to see whether (cross-border) infiltration stops, whether terrorists continue to get arms and refuge.

"India will decide its future course of action on the basis of these responses," warned the hardline Hindu Nationalist leader, who recently visited the U.S. to garner support for New Delhi's campaign against Islamic insurgency.

"Ninety percent of Musharraf's speech related to Pakistan and the internal problems it faces due to theocracy and religious extremism.

"There was little for India or our concerns in it," Advani insisted.

Musharraf last Saturday announced a crackdown on Islamic extremism and banned five radical groups. Since then almost 2,000 alleged militants have been arrested.

But India insists further visible steps must be taken before a dialogue can begin and is also seeking the extradition of 20 wanted criminals allegedly sheltered by Pakistan.

New Delhi accuses Pakistan of arming and deploying Muslim guerrillas into the Indian zone of Kashmir. Islamabad denies the charge but says it extends moral and diplomatic support to what it calls the Kashmiris' legitimate struggle for self-determination.

More than 35,000 people have died since 1989 in the Islamic separatist violence in Muslim-majority Kashmir, the subject of two of the three wars fought by the two South Asian adversaries since independence in 1947.
