Follow an earlier agreement signed in July 2015, on 25 January 2016 the Defense Ministers of Lithuania, Poland and Ukraine agreed to launch a joint brigade by January 2017, composed of 4000 forces. Talks have been going on already since 2007 but have been accelerated due to events in Ukraine in 2014 and 2015, which has increased concerns about Russia's behaviour in the region. The so called ''LITPOLUKR brigade'' is to take part in UN Peacekeeping Missions. The headquarters of the brigade is in Lublin, Poland.
