In his message to János Áder released on Monday, President Rouhani hailed the positive and productive changes in relations between Tehran and Budapest.
I hope for further promotion and deepening of ties between Iran and Hungary and more high-profile engagements between officials of the two nations, he said.
Rouhani also wished prosperity and dignity for the Hungarian president, government and people.
The Hungarian National Day called ' Nemzeti ünnep' is the memorial day of the 1956 Revolution (which – inter alia – aimed at the departure of the Soviet troops from Hungary and free elections).
It also marks proclamation of the Third Hungarian Republic (1989) in the Eastern European country.
