Russia consists of four geographic regions and controls much of Eastern Europe's natural gas distribution through Gazprom. There are wealthy Russians able to escape energy issues and those deceived by Moscow's schemes. Moscow makes up a large portion of Russia's economy and billionaires. Kazakhstan profits from oil and gas pipelines crossing its territory, pursuing a "multivector strategy" of relationships to avoid over-reliance on Russia. Mexico saw foreign investment increase after NAFTA but marginalized farmers protested, and its economy remains divided into northern, central, capital, and southern regions. Iran transitioned after the 1979 revolution from Persia to its current Islamic state, but still receives some international aid despite political instability limiting its development.
