Russia has ordered the closure of the Romanian consulate in St. Petersburg and declared the Romanian consul general *persona non grata*. This action was taken in response to Romania’s earlier decision to close a Russian diplomatic facility in the Romanian port city of Constanta. The Russian government framed the move as a retaliatory measure, mirroring Romania’s actions. Details surrounding the specific reasons for the initial closure in Constanta were not immediately provided in the announcement. The expulsion and closure signal a further deterioration in diplomatic relations between the two countries. Both actions represent a reciprocal downgrading of diplomatic presence. This escalation follows a pattern of similar exchanges between Russia and several other nations amid ongoing geopolitical tensions.
