A year after Russia’s invasion of Ukraine, the war is deepening the division among the world’s major economies, threatening fragile recoveries by disrupting food and energy supply chains and distracting from plans to combat poverty and restructure debt in poor countries.

Those fissures were evident this past week as top economic policymakers from the Group of 20 nations gathered for two days at a resort in Bengaluru, a city in southern India, where efforts to demonstrate unity were overshadowed by flaring tensions over Russia. During the summit, Western nations imposed a barrage of new sanctions on Moscow and unveiled more economic support for Ukraine, while developing countries like India, which have been reaping the benefits of cheap Russian oil, resisted expressing criticism.

The differing views left officials struggling to cobble together the traditional joint statement, or communique, on Saturday, forcing senior representatives from the Group of Seven nations, the world’s most advanced economies, to try to convince reluctant counterparts that defending Ukraine was worth the cost.
