Leader of Svoboda (Freedom) Party's faction in parliament Oleh Tiahnybok has said that a top-level meeting of the Ukrainian and Russian leadership in Moscow on Tuesday foresees discussion of Ukraine's cooperation with the Customs Union members.

"A number of documents will be signed in Moscow… According to our information, certain top-level meetings are scheduled. Ten issues will be covered at these meetings, of which the second agenda item will be the cooperation of Ukraine with the Customs Union," Tiahnybok said at the Monday briefing at the National Resistance Headquarters in Kyiv on Monday.

However, he said that it has been unknown yet whether any documents concerning the Customs Union will be signed.

"We don't know yet whether any documents will be signed," the Svoboda leader said.

Tiahnybok also noted that a rally with many thousands in attendance entitled "Say No to Customs-Taiga Union" will take place on Independence Square on Tuesday at 1800.

Earlier Ukrainian Prime Minister Mykola Azarov said that cooperation between Ukraine and the Customs Union won't be discussed during the sitting of the Ukrainian-Russian interstate commission in Moscow on December 17.
