India said Friday it was open to talks with Pakistan but no meaningful progress could be made until Islamabad controls the "terror machine" operating on its soil. Indian Prime Minister Manmohan Singh said he was a strong advocate of dialogue with Pakistan but Islamabad must not allow territory under its control "to be used for terrorism against India." "For any meaningful dialogue to proceed the terror machine has to be controlled by Pakistan," he told parliament. Singh's statement came a day after Pakistan said it had put forward a road map on how to revive talks with India's political leadership and had urged New Delhi to respond to the proposal. The prime minister did not comment on the Pakistani plan but said: "I have never believed channels of communication with Pakistan should break down... the chances of miscalculation can only increase in a situation of no contact." Senior officials of the two nuclear-armed South Asian rivals met in New Delhi last week for the first talks since a shaky India-Pakistan peace process was suspended following the deadly 2008 Mumbai attacks which New Delhi and Washington blamed on Pakistani militants. The civil servants agreed to keep in contact but made no progress on core disputes leaving both sides at loggerheads on how to take the dialogue forward. Pakistan has complained about India's "narrow focus" on terrorism and has called for a resumption of the full-blown peace talks. Singh in the past has said peace talks can only resume if Islamabad brings the Mumbai perpetrators to justice and cracks down on militant groups operating on its soil. Singh, responding to criticism from the opposition that India had restarted talks with Pakistan only because of US pressure, said the decision had been a "calculated one." "The fact is that the rest of the international community is talking to Pakistan. Not talking to them will not isolate them," Singh said.
