Afghan President Hamid Karzai is visiting Pakistan, and one of the issues on the table is a rather audacious Pakistani offer to train the Afghan National Army.

The Pakistani and Afghan security establishments have had a rather uneasy relationship, stemming from Pakistan's long-running ties to the Taliban.

For the Pakistani army to be now offering to train the Tajik-dominated ANA - which is fighting the  Pashtun Taliban - is quite a shift in its approach to the neighbour.

Or is this the latest battleground for the tussle for influence between India and Pakistan?

India has for years been running courses at its defence institutions which small groups of Afghan officers have attended. In recent years, several security experts have urged New Delhi to get more directly involved in training the new Afghan army, triggering concern in Islamabad.
