Solana is due to meet leaders of Serbia-Montenegro before traveling to Kosovo on 6 December.
Montenegro's government plans to hold a referendum in 2006 on separating from Serbia. The two republics formed a loose union in 2003.
In the breakaway Serbian province of Kosovo, the ethnic Albanian majority wants an independent state, an idea that Belgrade strongly opposes.
The security situation in Kosovo was thrown into the spotlight on 4 December by a failed rocket attack on a Belgrade-bound bus carrying ethnic Albanians, Serbs, and others to Belgrade. Kosovo's Prime Minister Bajram Kosumi has condemned the attack, saying on 5 December that the attack was an attempt to increase tensions in Kosovo.
Spotlight On Kosovo
THE WORLD'S NEWEST NATION? The region of Kosovo has a population of more than 2 million, some 90 percent of whom are ethnic Albanians. It was one of the poorest regions in the former Yugoslavia, but has considerable mineral wealth and an enterprising population, many of whom work abroad but keep close contact with Kosovo. All ethnic Albanian political parties seek independence on the principles of self-determination and majority rule. They feel that Serbia lost its historically based claim to what was its autonomous province under the 1974 constitution by revoking that autonomy in the late 1980s and then conducting a crackdown in 1999 that forced some 850,000 people to flee their homes.
Since NATO's intervention that year to stop the expulsions, Kosovo has been under a UN administration (UNMIK). The UN has begun to gradually transfer functions to elected Kosovar institutions. The primary Serbian concerns are physical safety for the local Serbian minority, a secure return for the tens of thousands of Serbian displaced persons, and protection for historic Serbian religious buildings. The main problems affecting all Kosovars, however, are economic. Until Kosovo's final status is clarified and new legislation passed and enforced, it will not be able to attract the investment it needs to provide jobs for its population, which is one of the youngest and fastest growing in Europe. Prosperity is widely seen as the key to political stability and interethnic coexistence in Kosovo, as is the case in much of Southeastern Europe.
