Russian President Vladimir Putin has claimed that Russia's economy has surpassed all European countries and is now the largest economy on the continent in terms of purchasing power parity. According to Russian media outlet TASS, Putin made this statement during a meeting with entrepreneurs in Russia's Far East.
PPP is a far more relevant metric for less globalized economies which are less reliant on foreign imports.
Whereas Russian imports are 15.6% of GDP and Chinese imports are 17.5% of GDP, imports in Western countries (UK, Canada, France, Germany, Spain) make up about 40-50% of GDP on average.
