If a demand to recognize Kosovo were to be "delivered" as a condition for Serbia's accession to the EU that would "be a high price to pay."

Tanjug is reporting this quoting philosopher and senior official of Alternative for Germany, Marc Jongen, whose party, according to estimates, will not only enter the German parliament in the next election, but is set win between 10 to 12 percent of the vote.

"It is difficult to give advice, but I believe in that case, the people should decide in a referendum whether Serbia is ready to pay that price," Jongen told the daily Politika.

Commenting on objections coming from Brussels that Belgrade is not following the foreign policy course of the EU because it is refusing to join anti-Russia sanctions, the German opposition politician said:

"If I may give advice to Serbia, I would tell it not to succumb to pressure and not to impose sanctions on Russia. Your country needs to maintain good relations with Russia and stay in that middle ground, because it is important for your economy."

Jongen added that it was important for the EU to have a bridge, such as Serbia, that connects Europe and Russia.

"It's not good to burn all bridges between Europe and Russia," he said.
