Pakistan's Foreign Office has already recommended that Sharif should accept India's invitation to attend the swearing-in ceremony of Modi.
"It will be a mistake to let this opportunity go. We need to see beyond today," a senior diplomat at the Foreign Office was quoted as saying.
"The Foreign Office has made the recommendation and the decision will most likely be in favour," the official said.

Meanwhile, Leader of Opposition in the National Assembly Khurshid Ahmed Shah has also urged Sharif to accept the invitation in the larger interest of the people of two countries.
Talking to reporters, Shah said such a gesture would help improve the situation in the region and the people in both countries would heave a sigh of relief.
"Better relations between India and Pakistan are in the interest of the poor people in both the countries," he said, adding that it was time that the two countries worked for development of their nations instead of focusing on fights.
As the suspense mounted amid reports that he was weighing all options, Sharif's daughter Maryam tweeted that cordial relations with the new Indian government should be cultivated.
"I personally think cordial relations with new Indian government should be cultivated. Will help remove psychological barriers, fear & misgivings," she tweeted.
She followed it up with another tweet, "It's upon the leaders to lead their countries & ppl to peace & conciliation."
This was read by analysts as a possible indication of her father's desire to travel to India.
The invitation for Sharif has sparked a debate in Pakistan on whether it should be accepted or not, particularly in view of strains in bilateral ties and non-acceptance of Pak’s invitation by Indian Prime Minister Manmohan Singh in the past, the report said.
It is to be noted that Sharif had called Modi to congratulate him on his party's election victory and invited him to visit Pakistan after assuming office.
