historically

Lmfao the USSR directly funded and supported emancipatory movements all over the world, like Vietnam, Cuba, Korea, Bangladesh, Palestinian resistance organizations like the PFLP, etc; even directly supplied wars against "israel" for that last one. Afganistan is about the only one where the US and USSR funding opposite sides turned it into a warzone instead.

Russia's interests are still broadly aligned with most of the world against Imperial core countries. While they're not socialist anymore and have thus stopped funding Vietnam, PFLP etc because it's not profitable for the capitalists that are now in power since the USSR's overthrow, they continue to support the sovereignty of Global South countries like Syria, Venezuela, etc, and are a core part of BRICS. There's a reason sentiment like this is common in third world countries.

And if "Global South" sounds too academic for you... I'm not sure what to say.

Russia's economic integration has undoubtedly been with the Global South in recent years. What, exactly, are you disputing from OP's comment?
