Official sources said Singh is unlikely to meet his Pakistani counterpart Chaudhry Nisar Ali Khan separately as top echelons of the government feel that time is not conducive for a bilateral meeting.
However, the Home Minister, in his speech at the SAARC meeting, is expected to raise the issue of Pakistan's support to terror groups operating in India and ask Islamabad to check Lashkar-e-Taiba, Jaish-e-Mohammad and other groups based in that country.
Not only did Sharif praise Wani but he also remarked that "Kashmir will one day become Pakistan", a comment which evoked a sharp reaction from External Affairs Minister Sushma Swaraj, who said his dream of the state becoming a part of his country "will not be realised even at the end of eternity".
Singh is also likely to raise the issue of fake Indian currency notes being circulated at the behest of Pakistani agencies, sources said.
