Romania’s Foreign Minister Oana Țoiu summoned Vladimir Lipaev, the Russian ambassador to Bucharest, to the Ministry of Foreign Affairs on Tuesday.

The summons represents a significant hardening of Romania’s diplomatic posture toward Moscow, signaling that Bucharest is no longer willing to maintain a low-profile approach to bilateral disputes.

The move by the Romanian government comes at a time of heightened diplomatic activity across the region.

In a parallel development, the Russian Foreign Ministry summoned Lilian Darii, Moldova’s ambassador in Moscow, on Monday to deliver a formal protest regarding alleged violations of the Vienna Convention.

This reciprocal summoning of diplomats underscores a deepening rift between Moscow and its western neighbors.

Tensions have been building for weeks.
