"Ukraine should have announced suspicion of involvement in economic crimes to those persons to resume sanctions imposed against them. I was especially frustrated to see Kliuiev Jr. on that list. Mezhyhiria, the main evidence of Yanukovych economic crimes, was titled in his name. Kliuiev continues to attend parliamentary sessions as if nothing had happened. According to sources, it is necessary at least to make a submission to the Parliament on stripping Kliuiev of immunity to preserve sanctions against him. But it has not still been done," Leshchenko wrote.
