We have reached an agreement to build a dual-lane highway between the eastern industrial regions of Hungary and Poland and to strengthen existing railway connections, Orbán said at an afternoon press conference, adding that the specific details of the agreement still have to be worked out.

The two parties are also committed to launching direct flights between Hungary and Poland, to depart from either Warsaw or Katowice, Orbán said.

Beata Szydlo said she expects economic and political ties to grow stronger as they plan to complete important infrastructural investment projects and enhance energy cooperation.
