Addressing his fellow heads of state and other high officials, Berzins said Latvia "strongly condemns Russia's intervention in Ukraine" which is "a clear violation of international law."
"Latvia strongly supports Ukraine's territorial integrity and sovereignty. We do not recognize and will not recognize the occupation of Crimea by the Russian side... We condemn any Russian attempts to create more 'frozen conflicts' in Europe," Berzins said.
In practical terms Latvia is providing both financial and humanitarian support to Ukraine, he continued, and in future will provide special mine clearance courses to Ukrainian personnel, Berzins concluded.
The NATO summit continues Friday with the US and EU expected to announce further economic sanctions against Russia.
