"On February 17, 2008, Kosovo declared its independence from Serbia. The United States and 22 of the 27 European Union countries have recognized Kosovo's independence. The Kosovo government claims that 98 countries in all have extended diplomatic recognition to it. EULEX, a European Union-led law-and-order mission, is tasked with improving the rule of law in Kosovo. KFOR, a NATO-led peacekeeping force that includes more than 700 U.S. soldiers, has the mission of providing a secure environment. Serbia strongly objects to Kosovo's declaration of independence. It has used diplomatic means to try to persuade countries to not recognize Kosovo. It has retained parallel governing institutions in Serb-majority areas in Kosovo. Since March 2011, the EU has mediated negotiations between Serbia and Kosovo. The agreements reached include ones on free movement of persons, customs stamps, recognition of university diplomas, cadastre (real estate) records, civil registries (which record births, deaths, marriages, etc. for legal purposes), integrated border/boundary management, and on regional cooperation. However, the accords have not been implemented or only partly implemented."
