New Delhi attaches immense significance to the visit.
"This is a very important visit. Afghanistan is an extremely important country for India and the two share close cultural and historical links," Foreign Secretary Shyam Saran said ahead of the visit.
Saran noted that Afghanistan was strategically very important for India and it was ready to give full support, including expanding security cooperation, to help Kabul deal with "newly-emerging threat" from the remnants of the Taliban still based in Pakistan.
"We want Afghanistan to emerge as a democratic, independent, sovereign country, in full mastery of its own destiny.... It is in our interest to ensure that Afghanistan does not once again become a kind of centre of extremism or terrorism. Anything that threatens Afghanistan's stability is a matter of concern for us," the Foreign Secretary said.
India has already trained 800 Afghans in policing and supplied 300 trucks for its military use.
Since the Karzai government took over nearly two years ago, India has been providing a broad-based support to Afghanistan aimed at its political and economic stability.
India is providing assistance worth $ 500 million to Afghanistan, most of which is focussed on building its infrastructure and social sector, including health and education.
