Under Sharif, the relationship between Pakistan and India might also improve, Wang Dehua, head of the South and Central Asian Studies Institute at the Shanghai Institute for International Strategic Studies told state-run Global Times said.
"In 1999, Sharif managed to invite then Indian prime minister Atal Behari Vajpayee for a historic visit to Pakistan," Wang noted.
Prime Minister Manmohan Singh wrote on his official Twitter page yesterday that he hoped to chart "a new course for the relationship" between the nuclear-armed neighbours.
Aside from foreign policies, Sharif will also have to face major domestic challenges including improving economic development and energy security.

"Compared to his predecessors, the advantage for Sharif is that he can create a stronger government as he does not have to form a coalition with major opposition parties," Wang said.
With Sharif return to power the future of Pakistan's strategy for the war against terrorism and its relationship with the US will be on in focus, Fu Xiaoqiang, a professor on South Asian affairs at the China Institutes of Contemporary International Relations, told the daily.
China welcomed Sharif's victory and its Premier Li Keqiang would be among the first foreign dignitaries to meet Sharif as he would visit Islamabad next week after his visit to India.
Observers believe that Sharif is actually taking a more pragmatic approach regarding Islamist militancy and Pakistan's relationship with the US, which could be seen by the fact that he was less vocal against US drone strikes compared to cricket star Pakistan Tehreek-e-Insaf party leader Imran Khan, Fu said.
