The virtual meeting featured security aides from Shanghai Cooperation Organisation (SCO) member states. India’s delegation, led by national security advisor Ajit Doval, quit the event after Pakistani representatives displayed a map depicting disputed territory as belonging to Islamabad.
The Pakistani map showed all of Kashmir, the sovereignty of which is hotly contested, as being under their authority.
According to the Times of India the New Delhi team dropped out of the event after seeing the Pakistani flag.
Muslim majority Kashmir is currently divided between Indian and Pakistani zones.
Since 1989 an armed insurgency has been taking place in Kashmir against Indian control.
Up to 100,000 are estimated to have been killed in the conflict.
The SCO meeting, which incorporates a number of regional powers, was being chaired by Russia.
The Russian delegation tried to persuade their Pakistani counterparts to remove the map but without success.
