Montenegro, the most recent state to join the United Nations (2006) is facing new challenges in politics due to its considerable ethnic diversity: Croats, Roma and Bosniaks are the main minority communities in the country. US-based 'Project on Ethnic Relations' has released a report [pdf] on "Developing a Minority Policy for Montenegro” summarizing the conclusions drawn from a roundtable discussion held on 14-15 December 2007 in Podgorica, Montenegro.
