Political influences between the countries are minimal, but social democrats tend to cooperate very closely on regional and European topics in recent years. Furthermore, it has become customary that the elected presidents pay their first and last official foreign visits during their term to the other republic of the former Czechoslovakia. Appointed foreign ministers tend to follow that unwritten rule. On October 29, 2012, to commemorate Czechoslovakia's declaration of independence, which occurred on October 28, 1918, the Czech and the Slovak governments held, for the first time, a joint cabinet meeting in the communities of Trenčín and Uherské Hradiště, near the common border.
