KYIV, Sept 23 – Investors’ key concern about President Volodymyr Zelenskiy is his allegedly close ties with billionaire Ihor Kolomoisky, Tomas Fiala, the president of the European Business Association (EBA), said Monday.

"Unfortunately, today he is the biggest negative factor that focuses a lot of attention on itself, starting with its statement to the Financial Times late May that Ukraine should default," Fiala said.
