Pakistan Television (PTV) repeatedly showed footage of Modi and Sharif seated together and exchanging views.
PTV reported that the meeting was held in a "cordial atmosphere" which it said was a "positive and happy occasion".
Modi and Sharif shook hands in a lobby of the Conference Centre in the French capital and then sat down on a sofa where they were seen talking animatedly.
The exact details of the talks were not known but there is expectation here that it will help to ease tensions between the two nations after the planned meeting of their national security advisors was cancelled in August.
