Here are 10 developments in this story:
PM Modi was flown in an Indian Air Force chopper while other leaders were taken by Nepal Army helicopters to a resort in Dhulikhel for the traditional retreat that provides an informal setting for discussions over breakfast and lunch.
In images tweeted by foreign ministry spokesperson Syed Akbaruddin, PM Modi was seen standing in a group that also included Mr Sharif. They were also seen flanking Nepal Prime Minister Sushil Koirala in a group photo.
PM Modi and Mr Sharif have shared frosty vibes since the two-day summit began on Wednesday and did not even look at each other when they shared a dais in the opening session.
The retreat was seen as a chance for other SAARC leaders to persuade Mr Sharif to change his mind on agreements that he has opposed, forcing the cancellation of a signing ceremony.
Pakistan has blocked key proposals to integrate energy grids and free up road and rail movement. Sources say SAARC nations are keen that at least the energy pact wins consensus, to avoid a total collapse of the summit. Indian spokespersons have said they are disappointed with Pakistan's stalling of the deals.
The Pakistani premier will fly out of Nepal this evening, a little earlier than scheduled. He will miss a banquet and a meeting with the Nepal President.
In his address in the opening session of the two-day summit, PM Modi had bluntly said SAARC evoked cynicism and skepticism, and offered his suggestions to improve connectivity in the region. "As SAARC we have failed to move with the speed that our people expect and want. Nowhere in the world are collective efforts more urgent than in South Asia; and, nowhere else is it so modest," he said.
In its 30 years, SAARC or the South Asian Association for Regional Cooperation, has delivered negligible results for economic ties and development among its members - Afghanistan, Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan and Sri Lanka.
Despite a free trade pact since 2006, South Asian nations conduct only 5 per cent of their total trade with each other, and there are few transport and power links among them.
PM Modi has had two-way talks with every other country except Pakistan as neither neighbour is ready to seek talks after 20 civilians were killed in recent firing along the border in Jammu and Kashmir.
