BUDAPEST, Hungary — Hungary and Slovenia are urging the European Union to speed up Serbia’s membership negotiations.

Hungarian Prime Minister Viktor Orban and Marjan Sarec, his Slovenian counterpart, also expressed disappointment Monday that the EU recently failed to agree on launching membership negotiations with Albania and North Macedonia.

Orban said the part of the Balkans that’s still outside the European Union “can’t be pacified and stabilized without Serbia’s development.”

The two leaders also agreed on the need to help reduce migration to Europe by increasing aid to regions that migrants come from. Both countries have a joint program to send medical supplies to Africa.

Orban also said there are currently 96,000 migrants on the move between Turkey and Hungary, heading “at different speeds” along the Balkan route toward Europe’s prosperous heartland.
