Russia could also just make energy cheap within their own country. Not ridiculously so, and not for everyone - but for utilities, and particularly, industry.
Energy use and GDP are in a nearly perfect 1:1 ratio. You can’t have an economy without it.
Cheap energy for manufacturers would attract a lot of global manufacturing and development. China did it with cheap labor, but they are losing that advantage, and China doesn’t have cheap energy. Russia could do it with energy.
Interesting Idea.
It is already cheap and it is not news — this has been case for years.
And this already led to Europeans (Germans in particular) building various plants in Russia. Naturally this stopped now (sanctions) but the fundamentals did not change.
