ASTANA, Dec. 18 – The doors of the Customs Union are open for Ukraine, and everything depends on the country's desire to adopt all of the principles and rules of the organization, Kazakh Foreign Minister Yerlan Idrisov said.

"As for Ukraine, I would like to note that the principle of the Customs Union and the Common Economic Space is very simple: we are open for membership and other forms of interaction with third parties. If Ukraine expresses the desire to accede to all the principles and agreements of the organization - the doors are open," Idrisov said in an interview with Interfax-Kazakhstan.
