ODESSA, Oct. 9 - The Russian Federation's claims against Ukrainian cheese producers are not without foundation, Prime Minister Mykola Azarov said in Odessa on Tuesday.

The Ukrainian government has done a review and established that some cheeses do not meet quality standards, Azarov said.

In the context of determining a format for cooperation with the Customs Union, Ukraine wants to coordinate unified quality standards with Russia and together with the country exercise control over product quality, the prime minister said.
