EU foreign policy chief Kaja Kallas said the bloc could tighten visa rules for Russians, including tighter controls on Russian diplomats' movement within Schengen, a ban on visas for former combatants, and fewer tourist visas for Russian citizens. In separate remarks, Kallas said she would be willing to answer a call from Vladimir Putin or Foreign Minister Sergei Lavrov if one came. The statements reflect the EU's balancing act between hardening restrictions on Russia amid the ongoing war and keeping diplomatic channels open for potential negotiations.
