One of his first acts was the establishment, in 1967, of the Orchestre de Paris, appointing Charles Munch as its first director. He also championed the establishment of regional orchestras at a time when interest in them appeared to be waning. This was part of a so-called "ten-year plan for music", instituted with the intention of establishing an opera company and conservatoire in each of the Regions of France. The new Orchestre de Paris was also built on the model intended to be followed by planned regional orchestras. In this endeavour Landowski worked with local authorities, especially those in the regional centres such as Bordeaux, Lille, Lyon, Strasbourg and Toulouse, who signed agreements under which the French State would finance a third of each company or ensemble's operating budget. Landowski also oversaw modernisation of regional concert halls and theatres.
