The meeting between Krishna and Khar took place on the sidelines of the international conference on Afghanistan in the Japanese capital.
Krishna raised the disclosures made by Abu Jundal, which corroborate claims of David Headly, another 26/11 plotter now in the US custody, about the involvement of Pakistani state actors in the 2008 attack. The issue figured prominently in discussions between Indian Foreign Secretary Ranjan Mathai and his Pakistani counterpart Jalil Abbas Jilani in New Delhi this month. India had then asked Pakistan to act on the information on Jundal's disclosures and underlined that bringing perpetrators of 26/11 carnage to justice would be the biggest confidence building measure between the two countries.
Pakistan has denied the involvement of state actors in the Mumbai attack and offered a joint probe into Jindal's disclosures.
