"After making a failed attempt to buy peace with Pakistan at New York, the UPA government has now allowed Pakistani Prime Minister Nawaz Sharif's advisor Sartaj Aziz to meet and hold talks with Kashmiri separatist leaders in New Delhi," he said in a statement.
"Why Aziz is given this opportunity when Pakistan is committing acts of aggression in the state of Jammu and Kashmir?" Singh asked and added that this is something blatantly against the established international diplomatic norms.
BJP demands that Aziz should be stopped from holding talks with Kashmiri separatists on Indian soil, he said, noting that Kashmir issue is India's internal matter and it should be resolved through a home grown solution.
Singh said that Pakistan has been trying hard to internationalise the Kashmir issue for many years and added that Kashmir issue was recently raised once again at the UN General Assembly meeting this year by Pakistan.
In the absence of a long-term strategic thinking and direction, the UPA government's Pakistan policy has been driven by adhocism, Singh said.
