Mr Varadkar hopes to discuss the progress that's being made in discussions on re-opening the Korean market for Irish beef exports.
They are also expected to discuss matters including Brexit and the evolving situation on the Korean Peninsula.
Prime Minister Lee will also pay a courtesy call to President Michael D. Higgins during his visit.
