Ukrainian and US officials continue to negotiate the terms of temporary ceasefires on Black Sea operations and energy infrastructure strikes, indicating the ceasefires are not yet fully codified. Ukraine's Ministry of Energy reported on March 26 that Ukraine and the United States agreed on a list of energy facilities that Russia must stop striking during an energy infrastructure ceasefire but that the US-Ukraine list is at odds with Russia's demands.[1] The Ministry stated that Russia's list does not prohibit strikes on Ukrainian oil and gas facilities — although the Kremlin reported that the ceasefire protects Russian oil and gas facilities from strikes. Ukrainian President Volodymyr Zelensky reported on March 28 that Ukrainian Defense Minister Rustem Umerov will present US officials with evidence of Russian ceasefire violations during Umerov’s upcoming trip to the United States.[2] The exact terms of the energy infrastructure ceasefire remain unclear, as an official trilateral statement or agreement has not been released.
Zelensky stated that Turkey, Bulgaria, the United Kingdom (UK), the United States, France, Romania, and Bulgaria could act as potential ceasefire monitors, including a Black Sea moratorium, but stated that all sides “will” hold internal and international consultations regarding “readiness” to conduct monitoring.[3] US Vice President JD Vance stated on March 28 that the United States and Ukraine have “obviously” achieved an energy infrastructure ceasefire and were “almost done” negotiating a maritime ceasefire.[4] US, Ukrainian, and Russian officials all appear to be under the impression that an energy infrastructure ceasefire is currently active despite the lack of a formal trilateral agreement or any apparent agreement on the exact terms of the ceasefire.[5]
European allies continue to provide financial and materiel support to Ukraine and agreed to expand intelligence sharing with Ukraine. Ukrainian President Volodymyr Zelensky announced on March 28 that European countries agreed at the “Coalition of the Willing” summit in Paris on March 27 to expand Ukraine's access to European intelligence, relevant technologies, and satellites and that several unspecified European countries agreed to grant Ukraine an unspecified degree of access to their ammunition stockpiles.[9] Zelensky noted that Ukraine also agreed with unspecified partners on air defense production licenses, investments in Ukraine's production of drones and missiles, and to continue to work toward artillery licensing. It remains unclear whether the agreed upon licenses stipulate domestic production in Ukraine or foreign production elsewhere in Europe. Zelensky stated that the United Kingdom (UK) and Germany will organize a Ramstein meeting in April 2025. French President Emmanuel Macron pledged on March 26 to provide Ukraine with an additional military aid package valued at 2 billion euros (roughly $2.1 billion) that will include anti-tank missiles, surface-to-air missiles, air defense missiles, armored vehicles, drones, and additional Mirage fighter jets.[10] Sweden instructed its armed forces on March 28 to allocate a total of 80 million Swedish Kronor (roughly $7.5 million) to Ukraine's Demining and Drone coalitions.[11] The Danish Ministry of Defense (MoD) announced on March 27 that Denmark pledged an additional 300 million Danish Kroner (roughly $43.5 million) to a Ukrainian innovation fund that will focus on, among other things, further developing electronic warfare (EW) and drone capabilities.[12]
The Russian MoD announced the launch of the “Indra Navy 2025” exercises in Chennai, India.[82] Russian Pacific Fleet Detachment Commander Captain First Rank Alexei Antsiferov stated that the drills will test joint Russian-Indian readiness and problem-solving at sea and will begin on March 31.
