ALMATY, June 26 -- Kazakhstan's Senate ratified an agreement Thursday between the Central Asian nation and Russia on cooperation in transporting Russian oil to China.

Kazakhstan and Russia signed the agreement to transport the Russian oil through Kazakhstan in December 2013.

Under the agreement, Kazakhstan agreed to provide long-term access to pipelines linking the three countries for the transport of 7-10 million tons of oil per year.

It is free to replace Russian oil with Kazakh oil, provided it is of the same quantity and quality specified in the contract with China.
