In early 2024, following the
2022 Russian invasion of Ukraine, several allies of Ukraine signed long-term bilateral security treaties with Ukraine for many years to come (often a period of 10 years). They resulted from a declaration by the G7 countries at a NATO Summit in Washington on 12 July 2023, concluding the establishment of a framework of bilateral security agreements of long-term military, materiel and economic support for Ukraine's defence. • 16 February 2024:

Similar agreements and negotiations In March 2024,
South Korea and Ukraine began negotiating long-term bilateral security agreements, later that year signing "a five-year framework agreement for USD 2.1 billion to support Ukraine's reconstruction projects". On 2 May 2025, Ukraine and the Republic of Korea signed an additional memorandum on deeper economic cooperation. In May and November 2024, the European Union signed "security and defence partnerships" with six countries, three of which (with Norway, Albania, and
North Macedonia), contained an explicit agreement on "(continued long-term) support for Ukraine". The EU–
Moldova Security and Defence Partnership of 21 May 2024 does not contain such a stipulation, but it does start by stating that both the EU and Moldova "face an increasingly challenging security environment inter alia due to ongoing Russia's war of aggression against Ukraine." By June 2025, when the three countries announced a "permanent coordination mechanism between the Ministries of Foreign Affairs", the trilateral framework (officially named the
Odesa Triangle since August 2025) on issues such as energy and transport infrastructure projects, business, border customs, combating Russian disinformation, and strengthening sanctions against Russia, was described by
GMFUS as a "mini-alliance of political and economic cooperation", although agreements on security issues had remained informal so far. ==Relations with CIS states==
