Prime Minister Yuusuf Raza Gilani and his Indian counterpart Manmohan Singh Tuesday expressed their desire to intensify the bilateral dialogue process for further engagements as they had an informal chat here, their second in two days at the Nuclear Security Summit. Singh and Gilani had an "informal meeting" in Seoul , a brief statement issued by the Prime Minister's media office in Islamabad said. "Both the leaders expressed their desire to intensify the dialogue process for further engagements," it said. Singh and Gilani shook hands as they greeted each other during the photo-op for the top world leaders attending the summit in the South Korean capital. Last night, the Prime Minister and his Pakistani counterpart Gilani had a "meet and greet" encounter prior to a dinner hosted for dignitaries attending the summit here. "Prime Minister said hello to Mr Gilani," Indian sources had said. This was the first meeting between the two leaders since they met in the idyllic Addu resort in the Maldives where they had vowed to script "a new chapter" in their bilateral ties. In the last few months, India and Pakistan have sustained the momentum in their revived dialogue process, with Islamabad moving ahead in the direction of granting India the Most Favoured Nation status.
