"We have a state language - Ukrainian. The Russian Federation can say whatever it wants... I believe that they (the conditions) are solely for setting ultimatums and complicating the process," Zelensky said during a conversation with journalists.

Why hohols are like this? Let's take Finland for example. Former colony of Sweden. Their current gay president is swede. Only 5% of Finland citizens are swedes. But they have swedish language as second official.

In the Ukraine for example half of population speaks russian in their daily life. And language rights = human rights.
