Prime Minister Manmohan Singh met his Pakistani counterpart Yusuf Raza Gilani informally several times during the course of the ongoing Nuclear Security Summit in Seoul. The two leaders decided to discuss all pressing matters facing the two nations and continue with bilateral talks, says Nikhil Lakshman, who is part of the media entourage accompanying the Prime Minister.

Singh was later seen having a longish chat with Chinese President Hu Jintao, who is set to visit India for the BRICS (Brazil, Russia, India, China, South Africa) summit in New Delhi this week.

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. 

"The Prime Minister said hello to Mr Gilani," Indian sources said. Singh and US President Barack Obama also exchanged peasantries and hugged each other when they came face-to-face t the summit yesterday.

Obama told Singh, "Nice to see you here Mr Prime Minister." The last Singh-Obama meeting had taken place on November 17, 2011 on the sidelines of the ASEAN summit in Bali, Indonesia.
