The Ukrainian Ministry of Foreign Affairs summoned John Hinkel, the interim U.S. Chargé d'Affaires in Kyiv, to discuss the suspension of U.S. military aid and defense cooperation amid ongoing tensions with Russia. The Ukrainian government warned that any delays in U.S. military assistance could embolden Russian aggression. This meeting follows the Pentagon's decision to withhold previously agreed-upon weapons deliveries. Additionally, Ukrainian President Volodymyr Zelensky has informed Ukraine's ambassador to the United States, Oksana Markarova, of his intention to dismiss her, though she may remain part of the team in another capacity. Foreign Minister Andrii Sybiha confirmed the ambassador's replacement, citing routine diplomatic rotation. Meanwhile, Ukraine's Foreign Ministry is establishing a new unit to counter threats from so-called "unfriendly countries," reflecting ongoing efforts to adapt to geopolitical challenges.
