"Only two percent of those who have illegally passed the Croatian border have been accepted back in Serbia-Montenegro. This is a problem which should be solved," Ambassador Stanicic told the 'Gradjanski List' daily published in the northern city of Novi Sad on Friday.
In this context the diplomat said Croatia's border with Bosnia-Herzegovina was much longer and that Bosnia admitted 98 percent of illegal immigrants when they were returned from Croatia.
The daily reports that Serbia-Montenegro has problems in the implementation of the readmission agreements which it has so far signed with another 14 countries.
The newspaper also quotes former Serbia-Montenegro foreign minister Goran Svilanovic as saying that visa regimes were a major problem in the region.
He recalled that Serbia-Montenegro's citizens could travel without visas only to Croatia, Bosnia and Macedonia, while they needed to apply for visas when travelling to other European countries. This is why about 70 percent of young Serbians have never been abroad, he added.
