The Kosovo leaders did not comment much on the plan, announced by the Serbian minister for Kosovo, Slobodan Samardjic, simply saying that it was not feasible.
Even the Prime Minister, Hashim Thaçi said that "the different plans or worse still ideas can be prepared in Belgrade, but it will always be seen as unacceptable".
Sejdiu said that they are "simply absurd".
As we have reported in recent days, Samardjic's proposal was sent to the United Nations Mission in Kosovo, UNMIK and the United Nations headquarters in New York to be evaluated.
The Serbian government has refused to recognize the independence of Kosovo, when it was declared a February 17 and was formally recognized by the United States and other countries.
Some ministers of the Belgrade government have condemned the request made by Samardzic because it has not been revised before.
The United Nations and NATO in Kosovo have accused the Belgrade authorities of their alleged involvement in last week's clashes in northern Kosovo, which left a UN police officer dead. Serbia denies involvement.
