• suspend or, failing that, cancel all events jointly arranged between CERN and institutions located in the Russian Federation and the Republic of Belarus.
• suspend the granting of association contracts as associated members of CERN personnel to any new individuals affiliated to home institutions in Russia and Belarus.
