Indian Congress chief Sonia Gandhi on Thursday strongly backed Prime Minister Manmohan Singh on the issue of the Indo-Pak joint statement and told partymen that there should be no confusion or misunderstanding on it among them. She also said that India's foreign policy vis-a-vis Pakistan has not changed. "Till Pakistan shows concrete steps on anti-terror front there is no point of dialogue," she told a Congress Parliamentary Party meeting here, a day after the Prime Minister addressed Parliament on the issue of the joint statement with Pakistan in Egypt. Resumption of dialogue with Pakistan depends upon whether it fulfills its promises on taking action against perpetrators of Mumbai attacks and does not allow its soil to be used for terror activities against India, Congress spokesperson Manish Tewari quoted Ms. Gandhi as saying in the meeting.
