British–Polish–Ukrainian trilateral pact

The British–Polish–Ukrainian trilateral pact (Polish: Trójstronny pakt brytyjsko-polsko-ukraiński, Ukrainian: Британсько-польсько-український тристоронній пакт) is an agreement between Poland, Ukraine and the United Kingdom announced in Kyiv on 17 February 2022 by Dmytro Kuleba, former Minister of Foreign Affairs for Ukraine, and Liz Truss, Foreign Secretary for the United Kingdom. The pact serves to improve cyber security, increase energy security, and counter disinformation. The creation of the new London-Warsaw-Kyiv axis took place against the background of Russian military buildup before the 2022 invasion of Ukraine and the active supply of weapons by the United Kingdom and Poland to Ukraine.

Cooperation between the three countries was originally initiated by Ukraine in October 2021. The formation of an alliance was revealed on 1 February 2022. The announcement of the security pact was originally scheduled for 2 February, but it was delayed until 17 February.

This unnamed pact is a part of Ukraine's broader strategy to form small alliances: the Lublin Triangle (Ukraine–Poland–Lithuania), the Association Trio (Ukraine–Georgia–Moldova), and the Quadriga (Ukraine–Turkey).
