Former Ukrainian President Leonid Kuchma (1994-2005) has said he doubts that the economic component of agreements with the Customs Union countries will be implemented.

"Where is the confidence of the Ukrainian side that the Customs Union will not be in the same situation?" he told journalists in Kyiv on Wednesday, noting that economic agreements were earlier signed with a number of countries, which are now part of the Customs Union, in particular, with Russia and Kazakhstan, which subsequently did not work.

Kuchma also said that economic relations between Ukraine and Russia are currently over-politicized.

"Politics outweighs normal economic market relations between the two countries... Let politics not jump the gun and not make the relations that they exist now. Let's go down to the ground, and let Ukraine and Russia sit down at the table and resolve problems one-on-one, rather than through the media," Kuchma said.

At the same time, he said he was confident that it is necessary to exclude ultimatums in Ukraine's foreign relations with the Customs Union and the European Union.

"Politics should be without ultimatums. Then everything will be fine," Kuchma said.

He also believes that the Ukrainian authorities, while choosing Ukraine's foreign policy vector, should take a strategic decision.

"We cannot live between the hammer and the anvil. We need to join a certain side," Kuchma said.
