Russia is the 4th largest economy by GDP, adjusted to PPP, and isn't as heavily reliant on finance capital as the EU is. Moreover, Russia has no colonies nor neocolonies, and doesn't run their economy based on export of capital and plundering the surplus value of the global south, like the US and EU do.

Imperialism is characterized by the following:

-The presence of monopolies which play a decisive role in economic life.

-The merging of bank capital with industrial capital into finance capital controlled by a financial oligarchy.

-The export of capital as distinguished from the simple export of commodities.

-The formation of international monopolist capitalist associations (cartels) and multinational corporations.

-The domination and exploitation of other countries by militaristic imperialist powers, now through neocolonialism.

-The territorial division of the whole world among the biggest capitalist powers.

The global north, Europe included, uses this export of capital to super-exploit foreign labor for super-profits. It also engages in unequal exchange, where the global south is prevented from moving up the value chain in production, allowing the global north to charge monopoly prices for commodities produced in the same labor hours. Russia does not do this, it has a paltry sum of the world's finance capital, and this is proven by just how low their nominal GDP is compared to it's GDP adjusted to PPP.

The Russian Federation and the EU are both right-wing, but the EU is actively imperialist. The fact that progressive nationalist movements like the Alliance of Sahel States are kicking out European plunderers, and the PRC is presenting as an alternative to western domination, is exactly why conditions within the imperialist west are declining and causing a shift to the far-right. Austerity politics are enforced due to capitalist decay.

Russia is more imperialist than the EU

Tell that to roughly a quarter of the entire continent of Africa that lived or still lives under French imperial control
