Russia began a full-scale invasion of Ukraine in February 2022. The Russian government has strongly cracked down on any perceived opposition, and has imposed harsh laws to criminalize opinions that deviate from the official point of view. Police brutality is expected at protests. International sanctions imposed on Russia affect banking, imports, prices and cross-border transportation, and directly or indirectly other fields, including availability of medicines and other essentials.
