Weiss said this was an obligation Serbia would have to meet in order to join the European Union.
He maintained that the condition for the launching of negotiations on a Stabilisation and Association Agreement between Serbia and Montenegro and the EU was that Serbia reach bilateral agreements with countries in which expelled Germans and their families now live, "although officially nobody will put it like that".
Weiss said Serbia still had to settle the issue of the property of 100,000 Germans expelled after World War Two, but added it could be expected that the influential German lobby in the United States would request via its government that the settlement of the issue began as soon as possible.
Weiss said the step of the Croatian government, which is expected to sign a compensation agreement with Austria, was a "wise policy" and "one of the examples of possible cooperation with neighbouring countries which are influential in the EU".
According to the latest census, about 3,900 Germans live in Serbia, mainly in the northern province of Vojvodina.
During the early 20th century Kingdom of Yugoslavia, more than 400,000 Germans lived in Vojvodina.
