Hungarian Prime Minister Viktor Orban says critics should not spoil the growth and stability that Central Europe is building through cooperation.

On the second day of his two-day visit to Poland, Orban addressed a conference of historians devoted to Central Europe.

He also met with Jaroslaw Kaczynski, the powerful leader of Poland's ruling conservative Law and Justice party, for talks on the European Union's future. Both politicians oppose EU policy on migrants and on other issues and call for greater autonomy for the bloc's 28 members. Their stance has drawn strong criticism from EU leaders.

In his speech Orban said that Central Europe is Europe's most stable region and is in constant development.

"We will not allow our critics to mar this situation," Orban said.
