Mrs. Szili invited Seks to Mohacs to attend traditional Carnival festivities in this southern town near the border with Croatia.
She expressed her country's full support to Croatia's efforts to enter the European Union and promised that Hungary would offer full help to Croatia during the coming membership talks with EU officials.
Szili invited Seks to attend a summit of parliament speakers of EU member states in Budapest in May.
