Spanish Foreign Minister Josep Borrell said on Wednesday in Belgrade that the cases of Kosovo and Catalonia are not comparable. These two situations, he said, have nothing to do with one another. "Such comparisons fall on deaf ears. They have no weight, although advocates of Catalonia's independence like them," Borrell said in response to questions at a joint press conference with the Serbian Foreign Minister Ivica Dacic. Dacic said that all separatism have being guided by unilateral acts in common. "They do not want dialogue, and that is why it is unacceptable," Dacic said. He added that representatives of Catalan separatists opened their office in Zagreb, Croatia - but "have no business being here in Belgrade and Serbia." Borrell said he had invited Dacic to open an honorary or general consulate in Barcelona. "It is good to have institutions that help bilateral relations," the Spanish official said.
