Indian Prime Minister Narendra Modi called for a return to diplomacy to end the Russian-Ukrainian war at the G20 summit, echoing the South Asian country's call for peace in the conflict, Reuters reports.

 "I have said many times that we have to find a way to get back on track with the ceasefire and diplomacy in Ukraine," Modi said in his opening remarks at the G20 summit in Bali, Indonesia.

 "The need of the hour is to demonstrate a concrete and collective resolve to ensure peace, harmony and security throughout the world," he said.

 India did not condemn Moscow's invasion of Ukraine, but Modi told Russian President Vladimir Putin in September that "today's era is not an era of war."

 India has become Russia's biggest buyer of oil after China, with its refiners buying up crude oil at discounted prices that Western buyers shun.
