Viktor Orban said migrants were "breaking the doors" and that a united stance was required, BBC reported.
Ministers from Poland, Hungary, the Czech Republic and Slovakia met to discuss an EU proposal for quotas, which they oppose.
Some EU countries want migrants shared out more evenly across the EU.

Police in Greece, where many arrive on European shores, say 8,500 people have travelled north to Macedonia in the past day.
Austrian police said 24,000 migrants arrived over the weekend. Several thousand more were expected to arrive on Monday.
In Nickelsdorf on the Austria-Hungary border, where hundreds of people have been camped out, two buses have continued to arrive.
Most travelled in from Hungary and Croatia. Budapest is now rushing to finish a new fence along its Croatian border.
At a temporary camp in Opatovac, Croatia, angry scenes broke out in the early evening.
