The Spanish government would not accept Kosovo's declaration of independence, local media reported Sunday.

The ruling Spanish Socialist Worker's Party (PSOE) expressed its opposition to Kosovo's independence, saying it is beyond international laws for Kosovo to unilaterally declare its separation from Serbia.

It also said the declaration would harm peace in the Balkan region, setting a dangerous precedent for regions where separatism exits.

On Saturday, Fernandez de la Vega, Spain's First Deputy Prime Minister, had voiced Spain's opposition to Kosovo's independence.

Kosovo's parliament convened on Sunday afternoon and independence is expected to be proclaimed.

Kosovo is a cultural heartland of Serbia. But most of Kosovo's 2 million people are ethnic Albanians, who have been impatient with delays of the proclamation of independence.

Kosovo has been under UN administration since mid-1999, after NATO launched airstrikes to drive out Serbian forces from the province.

In April 2007, UN special envoy Martti Ahtisaari recommended the proposed internationally supervised independence for Kosovo.

The Ahtisaari plan is supported by the United States and the European Union, but opposed by Serbia and Russia.

Russia, a permanent member of the Security Council, has warned that Kosovo independence would set a dangerous precedent for regions across the world where there are ethnic tensions.
