This edition of HoA will be held in Amritsar in December 3 and 4.
It may be noted that India's External Affairs Minister Sushma Swaraj will not be attending the conference.
Advisor to Prime Minister on Foreign Affairs Sartaj Aziz will go to India to participate in the Heart of Asia Conference amidst escalating tensions between the two nuclear armed countries.
Afghanistan's Ambassador to India Shaida Abdali had recently said that the "Heart of Asia" governments had agreed that implementation of non-interference in Afghanistan requires "resolutely combating and eliminating terrorism; dismantling terrorist sanctuaries and safe havens; and acknowledging that terrorism is a threat to global peace and security".
Basit was also reported saying, "We can delay talks for months or even for years".
Aziz is expected to be accompanied by Pakistan ambassador to Afghanistan Syed Abrar Hussein. The attack came barely 24 hours after Pakistan high commissioner Abdul Basit seemed to reach out by declaring that Pakistan was ready for "comprehensive and unconditional" dialogue with India.
MEA Spokesperson Vikas Swarup said this while responding to a media query in New Delhi today.
"We are for a dialogue with Pakistan but talks and terror can not happen together", Swarup said.
Some experts believe that this participation is in interest of the country as Pakistan should not be out of the game. "This conference will have some substantive outcomes, and India will be firmly placed at the development matrix of Afghanistan", a government official said.
The two countries have also accused each other's missions in their capitals of spying for their intelligence agencies, and in recent days have engaged in heavy crossfire along the LoC, leaving dozens of civilians and soldiers dead on both sides.
