2007 Russia–Belarus energy dispute

The Russia–Belarus energy dispute began when Russian state-owned gas supplier Gazprom demanded an increase in gas prices paid by Belarus, a country which has been closely allied with Moscow and forms a loose union state with Russia. It escalated on 8 January 2007, when the Russian state-owned pipeline company Transneft stopped pumping oil into the Druzhba pipeline which runs through Belarus because Belarus was siphoning the oil off the pipe without mutual agreement.
