Russia has implemented a notification requirement for the travel of European diplomats stationed within the country, extending the rule to their adult family members. The measure, announced by the Russian mission to the EU in Brussels, mandates that diplomats inform Russian authorities of their movements. Details regarding the specifics of the notification process and the rationale behind the restrictions remain limited. This action follows a pattern of escalating tensions between Russia and European nations, particularly in the context of the ongoing conflict in Ukraine. European officials have yet to officially respond to the new regulations, but it is anticipated they will view the move as a further impediment to diplomatic efforts. The restrictions are likely to complicate the work of European diplomats and potentially lead to reciprocal measures from EU member states. This development signals a continued deterioration in diplomatic relations.
