The PC Chairs of CONCUR 2022 and the Steering Committee of CONCUR strongly condemn the Russian invasion of Ukraine, a violation of international law and a crime against humanity. We express our solidarity with the Ukrainian people in their plight, and our deep respect to their courage in defending their country.

We adhere to the statement of the European University Association (EUA). In view of disgraceful declarations of many Russian academic institutions, we support the decision, made by several international academic organisations, to freeze all institutional collaboration with the Russian academic establishment. Therefore we request academics from Russia, when submitting their work for CONCUR 2022, to consider refraining from mentioning Russian affiliations and acknowledging support from Russian institutions. We know that many Russian academics are actively opposed to the war against Ukraine and we acknowledge their civil courage.
