Montenegro on Thursday formally recognized the independence of the breakaway Serbian province of Kosovo, Montenegrin Foreign Minister Milan Rochen reported in the capital Podgorica, dpa reported.
With the unanimous decision by the government, Montenegro became the 50th state to recognize the mostly ethnic Albanian republic.
The US, Japan and nearly all EU states have already recognized Kosovo's independence.
Montenegro and Serbia was part of a common state until two years ago when a referendum to split the two entities was implemented.
Serbian Foreign Minister Vuk Jeremic had earlier called possible recognition of Kosovo by Montenegro a "stab in the back" for Serbia.
