International recognition of Macedonia's independence from Yugoslavia in 1991 was delayed by Greece's objection to the new state's use of what it considered a Hellenic name and symbols. Greece finally lifted its trade blockade in 1995 and the two countries agreed to normalize relations, although differences over Macedonia's name remain. The undetermined status of neighboring Kosovo, implementation of the Framework Agreement - which ended the 2001 ethnic Albanian armed insurgency - and a weak economy continue to be challenges for Macedonia.
