Odesa Triangle
The Odesa Triangle, also known as Moldova–Romania–Ukraine trilateral cooperation, the trilateral format, or trilateral forum, is a joint cooperation format between the Eastern European countries of Moldova, Romania and Ukraine since 2022. The trilateral cooperation format began with a 15 September 2022 ministerial meeting in Odesa in response to the February 2022 full-scale Russian invasion of Ukraine, consisting of a loose set of trilateral agreements and intergovernmental negotiations between the three countries that gradually became more permanent, until it was officially named the "Odesa Triangle" at the 8 August 2025 summit in Chernivtsi.
