Within Bosnia and Herzegovina, relations with its neighbors of Croatia, Serbia and Montenegro have been fairly stable since the signing of the Dayton Agreement. On 23 April 2010, Bosnia and Herzegovina received the Membership Action Plan from NATO, which is the last step before full membership in the alliance. Full membership was initially expected in 2014 or 2015, depending on the progress of reforms. In December 2018, NATO approved a Bosnian Membership Action Plan.
