"When the allegations of Pakistan's involvement first appeared, the Pakistan Rangers clearly conveyed to BSF through official channels that Pakistan had nothing to do with it. Pakistan Rangers also extended help in efforts to locate the soldier's body", said the FO statement issued on Friday night.
The foreign ministry in New Delhi blamed the about-face on recent actions that had revealed Pakistan's "evil agenda" and the "true face" of Khan, who hit back on Twitter Saturday.
Pakistan and India have an "undeniably challenging relationship", he said, while responding to Modi's letter to him on August 18.
"The latest brutal killings of our security personnel by Pakistan-based entities and the recent release of a series of 20 postage stamps by Pakistan glorifying a terrorist and terrorism confirmed that Pakistan will not mend its ways", said the statement by the Indian External Affairs Ministry.
Mr Khan had written to India Prime Minister Narendra Modi to call for a resumption of talks, in what would have been the first meeting in almost three years.
In the letter dated September 14, Khan also proposed a meeting between Foreign Minister Shah Mehmood Qureshi and his Indian counterpart Sushma Swaraj on the sidelines of the UN General Assembly in NY this month.
India has long accused Pakistan of arming Muslim separatists in the divided Himalayan territory of Kashmir, though both countries claim it in its entirety.

However, Pakistan, in response, maintained that the "disturbing developments" referred to in the Indian statement predated the Indian agreement to hold the bilateral meeting in NY, and claimed that India's comments against Khan were "against all norms of civilised discourse and diplomatic communication".
He added: "Pakistan remains ready to discuss terrorism".
Pakistan's foreign minister Shah Mehmood Qureshi blamed Indian politics.
Pakistan Information Minister Fawad Chaudhry said "an extremist segment in India doesn't want to see Pakistan and India move ahead on the path of dialogue to resolves issues".
The world was watching and the internal differences of India had come into the open, he said adding, "The world is saying that Pakistan is extending the hand of peace while India is rejecting it".
"Time and again we have said atmosphere in the region is not conducive for a summit".
