Let me express my sincere hopes that cooperation between our institutions - Taras Shevchenko National University of Kyiv, the leading Ukrainian educational and research hub, in Ukraine, and the University of Florida, will strengthen and grow. I would be happy if you would be interested to engage more Ukrainian scholars to discuss and to cooperate for best practices sharing and development of legal studies and internationalisation of Ukrainian law. The American experience is very valuable and important for us, who are seeking renovation and restoration of our state after this unbelievable war.
