The new language law will split Ukraine. There are a lot of national minorities in Ukraine, including Armenians. The new law will lead to even greater divisions and tensions and, moreover, will intensify conflict.
The language rights of national minorities have to be in line with Ukraine’s obligations under the European Charter for Regional Languages and Languages of National Minorities. This is guaranteed by a separate law, the draft of which the government must develop and submit to the Parliament six months after the law on the state language enters into force.
