Exclusion of Russia

With the 2022 Russian invasion of Ukraine, the participation of Russians with CERN was called into question. About 8% of the workforce are of Russian nationality. In June 2022, CERN said the governing council "intends to terminate" CERN's cooperation agreements with Belarus and Russia when they expire, respectively in June and December 2024. CERN said it would monitor developments in Ukraine and remains prepared to take additional steps as warranted. CERN further said that it would reduce the Ukrainian contribution to CERN for 2022 to the amount already remitted to the Organization, thereby waiving the second installment of the contribution.
