There is a view that yesterday's telephonic call by the Prime Minister to Sharif has "lowered the temperatures" between India and Pakistan which have been involved in a war of words over Modi's critical remarks about Pakistan during his Dhaka visit recently and in the wake of India's military action in Myanmar.
However, no official request for a meeting has been initiated from either side so far.
In his telephonic conversation, Modi had also conveyed to Sharif India's decision to release detained Pakistani fishermen on the "pious" occasion of Ramzan.
The annual SCO summit will be held in Ufa from July 9-10 and both India and Pakistan are likely to be granted full membership of the China-backed grouping.
India had formally applied for membership of SCO in its summit meeting in Dushanbe last year, saying it was ready to step up engagement with the grouping.
