Orban made his defence in front of the European Parliament just hours after the EU launched legal action against Hungary over the legislation targeting the Central European University in Budapest.
"We are not as big and powerful as you are, and not as big as powerful as George Soros, the American financial speculator attacking Hungary," Orban told MEPs in Brussels, defending his law.
Orban said Hungarian-born Soros "has destroyed the lives of millions of Europeans with his financial speculations" and "is an open enemy of the euro".
The latest feud with the EU marks a new low in the tense relations between Brussels and Budapest over the government's rights record.
