Ukrainian President Volodymyr Zelensky signed a security pact with the European Union at a summit of EU leaders in Brussels on Thursday.
Zelensky signed the accord in a ceremony alongside European Council President Charles Michel and European Commission President Ursula von der Leyen.
The agreement between the EU and Ukraine was drawn up after months of talks among the 27 EU member states to hammer out the pact to support the country's long-term security.
As well as new plans for closer cooperation between the defence industry in Ukraine and the EU, a new EU-Ukraine crisis consulting procedure forms part of the pact.
Should Russia attack Ukraine again after the current invasion, or use nuclear weapons during the ongoing war, the EU and Ukraine are to hold emergency consultations within 24 hours at the request of either party to discuss possible support.
