The Ukrainian language was recognized as the state languagein Ukraine in 1989. This preceded the signing of the Declaration on the State Independence of Ukraine in 1991. From that moment on, the Ukrainian language is considered a symbol of the new Ukraine. Raising the status of the Ukrainian language has become one of the central issues in the process of building an independent state. The UN Security Council discussion in July 2019 on the language policy in Ukraine showed the world community's concern over the problem of ensuring the rights and freedoms of citizens and national minorities in Ukraine in connection with the adoption of the Law on the legal status of the state Ukrainian language and its use in education and public life.
