Background

Katarína Mathernová became one of the war's most prominent diplomatic voices on 25 May 2026 when Russian Foreign Minister Lavrov formally demanded all Western diplomatic staff evacuate Kyiv. Her response — "We stay in Kyiv. We stay with Ukraine." — was quoted across international media alongside Ukrainian Foreign Minister Sybiha's similar rejection, and signalled that the EU mission would not be coerced into treating the capital as a target zone.

Mathernová is a Slovak-born lawyer who spent more than a decade as Deputy Director-General at the European Commission's DG NEAR (Directorate-General for Neighbourhood and Enlargement negotiations), and simultaneously led the EC Support Group for Ukraine from 2020 to 2023. She was accredited as EU Ambassador to Ukraine in September 2023, arriving in Kyiv at a moment when Ukraine had just launched its Zaporizhzhia counteroffensive. Before Brussels, she served as a World Bank senior adviser for Europe and Central Asia and was a key architect of Slovakia's post-communist economic transformation in the late 1990s. She holds a Juris Doctor from Comenius University Bratislava and an LLM from the University of Michigan.

Mathernová has stated this will be her final institutional posting. Her public defiance of the evacuation demand underlines the EU's broader posture in 2026: maintaining a physical, diplomatic presence in Kyiv is itself a policy signal, distinct from any specific financial or military commitment.
