EU foreign policy Chief Federica Mogherini will invite Aleksandar Vucic and Isa Mustafa to meet in Brussels after New Year's and Christmas holidays.

Belgrade-based daily Vecernje Novosti writes, quoting "EU diplomatic circles".

A new round of the Kosovo dialogue, in Brussels, should be scheduled after the Constitutional Court in Pristina take a decision on the constitutionality of the agreement on the Community/Association of Serbian Municipalities (ZSO).

The establishment of the ZSO has been temporarily suspended by the Pristina authorities.

It is expected that the Court will make its decision as early as Tuesday.

The newspaper reported that according to "assessments in Pristina" the court will say that the agreement is "not unconstitutional" because it was envisaged by the Brussels agreement, that was ratified by the Kosovo Constitutional Court and the assembly.

"That means it has the character of an international contract, that is - it takes precedence over the laws and the Constitution," the article said, adding the court is expected to recommend to the government in Pristina to pass a decree on implementing the agreement on the ZSO.
