Hungary is strongly critical of EU immigration policies, has built border fences to keep migrants out and rejects the bloc's obligatory quota system for taking in asylum-seekers.
"We should not speak about how to encourage migration, how to manage migration, we should speak about how to stop the migratory flows," Szijjarto said.
"Because if the migratory flows continue then that would pose a significant security threat (to) Europe." Friday's talks in a resort south of Athens brought together ministers from the so-called Visegrad Group Poland, the Czech Republic, Slovakia and Hungary and Greece, Bulgaria, Romania and Croatia.
Visegrad Group members strongly object to EU immigration policies, and resent criticism over the rule of the law in their countries from many EU partners.
Polish Foreign Minister Jacek Czaputowicz told the AP that while attitudes towards Poland from other European capitals and "elites" have improved, countries facing similar criticism should take common defensive action.
"Countries of the region, central and eastern Europe, should stay together," he said. "We have common interests, we cannot accept double standards within the European Union, and we have to defend our cause.
