The deal will be in force from January 2015 until the end of 2029, and will be automatically prolonged every five years after that, if neither of the sides objects, spokesperson for the Slovak Economy Ministry Miriam Ziakova told RIA Novosti Thursday.
Russia will supply Slovakia with about 6 million metric tons of oil annually under the new deal, which will replace the previous agreement that expires on December 31, 2014. The same amount of Russian oil will be delivered via Slovakia to Western Europe.
According to the US Energy Information Administration data, Slovakia's daily oil consumption stands at some 70,000 barrels. Russian oil is delivered to the country via the Druzhba pipeline, which also runs through Ukraine.
