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.On 10 January, Transneft resumed oil exports through the pipeline after Belarus ended the tariff that sparked the shutdown, despite differing messages from the parties on the state of negotiations.
