New Delhi, Aug 24 - Underlining India's pursuit of a peaceful and stable neighbourhood, External Affairs Minister S.M. Krishna Monday asked Pakistan to take 'effective steps' to dismantle the infrastructure of terrorism and stressed that popular aspirations are the bedrock of New Delhi's foreign policy.

Days after India gave a fresh dossier to Pakistan on the alleged involvement of Hafiz Saeed in the 26/11 Mumbai attacks, Krishna said that despite evidence given to Islamabad about the alleged complicity of Pakistani militants in the carnage, it was yet to take effective steps to stop infiltration and terror directed against India.

Krishna, while addressing Indian envoys to 112 nations who are here for a three-day conference, emphasised New Delhi's wish to resolve differences with Islamabad through dialogue.

'We have maintained that a stable Pakistan at peace with itself and the region is a desirable goal. We wish to address our differences with Pakistan through dialogue,' Krishna told the ambassadors who have gathered here to debate key foreign policy and strategic challenges facing the country.

'At the same time, we made it clear that a meaningful dialogue will only be possible following the fulfilment by Pakistan of its commitment not to allow its territory to be used for terrorist activities against India,' he maintained.

'Pakistan must honour the pledges made in this regard,' Krishna added.

Prime Minister Manmohan Singh is expected to interact with the envoys Tuesday. The conference of is the first such exercise after the ruling United Progressive Alliance (UPA) coalition returned to power in May.

Underlining India's increasing exasperation with Pakistan's failure to take effective action against the perpetrators of the Mumbai carnage, Krishna said: 'We are still to see Pakistan take effective steps to end infiltration and dismantle the infrastructure of terrorism.'

Krishna, however, acknowledged that Pakistan has taken 'some steps under the pressure of evidence' presented in the wake of the Mumbai attacks.
