Russia's economy: Putin's oil industry is in serious trouble. Gasoline production in Russia has fallen significantly after a series of attacks by Kiev on the country's oil refineries.

Russia is the third largest oil producer in the world, accounting for more than 12 percent of global crude oil production. Putin's government has banned gasoline exports for six months since March 1 to offset the rise in fuel prices in the country. The speed and quality of repairs will be the key indicators of Moscow's readiness to stop the drone attacks.
