Pakistan called on Monday for "sustained and meaningful" dialogue with India after Indian Prime Minister Manmohan Singh said a trust deficit was the main obstacle in ties between the nuclear-armed rivals. Speaking at a news conference in New Delhi, Singh said India was willing to discuss all outstanding issues with Pakistan but "the trust gap is (the) biggest problem". Pakistan said it agreed that mistrust should be dispelled. "Obviously, there is a mutual trust deficit and we need to build trust between our two countries on solid foundations so that our two countries and our people can live in peace and prosperity," said Pakistan foreign ministry spokesman Abdul Basit, reported a private TV channel. "To this end, Pakistan looks forward to a sustained and meaningful engagement with India with a view to free our relations from all disputes and conflicts", he said
