What is Russia's primary secondary and tertiary industry?

Russia's primary industry is largely centered around natural resource extraction, particularly oil and gas, which play a crucial role in its economy. The secondary industry includes manufacturing and processing, with significant sectors like heavy machinery, steel production, and chemical manufacturing. Tertiary industries involve services, including transportation, retail, and finance, although this sector is less developed compared to the primary and secondary industries. Overall, the economy is heavily reliant on its Natural Resources, which influence both secondary and tertiary sectors.
