Leader of Crimean Tatars Mustafa Jemilev spoke at the meeting with the European security body OSCE on May 8, in Vienna, AFP reports.
Jemilev appealed to international community not to forget the Black Sea peninsula, annexed by Russia, as attention has turned to growing violence in eastern Ukraine.
"We are concerned that because of Russia's recent actions, the issue of Russia's occupation of Crimea has become secondary in light of the potential threat of Russian forces invading across the eastern border of Ukraine,"- Jemilev said.
"We are in favour of being part of the Ukrainian nation, we reject this annexation," he said.
"We are hoping that the international community will not forget about the occupied territories of Ukraine," he added.
