The 2006 ban on imports of Georgian wine to Russia, one of Georgia's biggest trading partners, and break of financial links was described by the IMF Mission as an "external shock". In addition, Russia increased the price of gas for Georgia. Around the same time, the National Bank of Georgia stated that ongoing inflation in the country was mainly triggered by external reasons, including Russia's economic embargo. The Georgian authorities expected that the current account deficit due to the embargo in 2007 would be financed by "higher foreign exchange proceeds generated by the large inflow of foreign direct investment" and an increase in tourist revenues. The country has also maintained a solid credit in international market securities. Georgia is becoming more integrated into the global trading network: its 2015 imports and exports account for 50% and 21% of GDP respectively. Georgia's main imports are fuels, vehicles, machinery and parts, grain and other foods, pharmaceuticals. Main exports are vehicles, ferro-alloys, fertilizers, nuts, scrap metal, gold, copper ores.
