President Aleksandar Vucic told Prva TV on Tuesday that he would like Serbia to lobby more around the world for resolving the issue of Kosovo. So far, this has not been done, he added. Vucic earlier in the day in Belgrade received representatives of the German Bundestag, Peter Beyer and Christian Schmidt. Apart from bilateral relations, economic cooperation, the problems in the dialogue with Pristina was also discussed. Vucic told Prva TV after the meeting that he is always ready to listen to proposals coming from smart people - but that he at the moment does not see a solution that would allow continued dialogue with Pristina. Asked to comment on EULEX's decision to transfer war crimes cases to the Kosovo judiciary, Vucic replied briefly: "There is nothing to add there. (They're) judges in their own case. That's all we could expect and nothing more," he said. Commenting on reports that the Serbian Government had hired a US lobbying firm related to the Kosovo issue - which have been refuted - Vucic said that there was no contract on lobbying. "I spoke about this with the Serbian Government, the question was whether we would launch an arbitration procedure because of (Pristina's) taxes, but these were only conversations, there is no agreement," he said. Asked whether he would like Serbia too, like Kosovo, invest as much money in lobbying on issues of vital importance, Vucic said he would like Serbia to invest more money when it comes to ​​lobbying around the world.
