Russian President Vladimir Putin and his Ukrainian counterpart Viktor Yanukovych did not discuss Kiev's possible integration with the Customs Union (EU) during a recent meeting, the Kremlin said Saturday.

During their Friday meeting in the Russian city of Sochi, the two presidents discussed the agenda of an upcoming bilateral interstate commission scheduled on Dec. 17, but they did not talk about Ukraine's possible accession to the Moscow-led CU, the Kremlin press secretary Dmitry Peshkov said.

"Special significance was attached to cooperation in the energy field," Peshkov said, adding that they also considered the current state and future prospects of bilateral cooperation in the financial sector.

The two countries converged their positions in the talks, still, no final agreement was reached, Peshkov added.

The CU currently consists of Russia, Belarus and Kazakhstan, with Armenia on the "waiting list." Local experts said Armenia's way to the tripartite economic block could be shorter, as Moscow intended to integrate more ex-Soviet states into the Russia- dominated geopolitical entity, especially after Kiev decided to suspend its integration process with the European Union.

The Ukrainian government made a sharp U-turn on Nov. 21, a week before the long-anticipated summit in Vilnius, Lithuania, to put the deal on hold and sought to restore ties with Russia, sparking mass protests in the capital city of Kiev and other major cities.
