India said it was time for the international community to identify countries that promote terrorism and isolate them, in a thinly veiled denouncement of archrival Pakistan.
India's External Affairs Minister Sushma Swaraj, speaking at the UN General Assembly on September 26, said the international community needed to "join hands together to script an effective strategy against terror."
"If any nation refuses to join this global strategy, then we must isolate it," Swaraj added.
India accuses Pakistan of having a role in a September 18 raid on an army base in India-controlled Kashmir, one of the deadliest attacks in the disputed Himalayan region in years. Pakistan denies any role in the attack.
India's Prime Minister Narendra Modi pledged on September 24 to launch a global campaign to isolate Pakistan.
Last month U.S. Secretary of State John Kerry urged Pakistan to fight terrorism.
New Delhi has long accused Islamabad of supporting militant groups carrying out violence in India. Pakistan has rejected the allegations.
