A move in this direction by Chile would require strong political support and clear consensus. Housing, urban policy and municipal infrastructure were the responsibility of the Ministry of Infrastructure, which needed to co-ordinate with the Ministry of Internal Affairs and Administration, responsible for public administration matters, including supervision over self-government units (municipalities/gminns), counties (powiats) and self-government regions (voivodships). In addition, housing, urban policy and municipal infrastructure, as essential elements in urban planning, simultaneously needed to be co-ordinated with national level spatial and regional policy programming housed in the Ministry of Regional Development.
