The Austrian government has said it will sharply reduce the number of asylum applications it accepts this year compared with 2015.
Chancellor Werner Faymann said numbers would be capped at about 37,500 in each of the next four years, compared to the 90,000 applications last year.
Serbia responded by saying it would limit migrant passage to those seeking asylum in Austria or Germany only.
The head of the European Commission has called for a summit on migration.
Jean-Claude Juncker said he was worried there would not be enough time to address the issue at the next extraordinary summit of the EU’s 28 member-states, due on 18-19 February.
It is expected the UK’s membership of the EU will dominate that meeting.
The EU is drawing up plans to share the “burden” of refugees more evenly among member states, scrapping the rule that means they must claim asylum in the first country they arrive in.
