Together with Rotterdam, The Hague and Utrecht, Amsterdam aims to develop a Â'Delta MetropolisÂ' - an internationally orientated, economically strong agglomerate with a competitive environment for business location.
The four major cities (G4) will combine to promote mutual interests in the areas of urban planning, transport, public order, work and income, and social and cultural facilities. They aim to persuade national government to invest more in Amsterdam Schiphol Airport as a mainport, in the development of Rotterdam harbour, and in key projects such as the Amsterdam Zuidas, Rotterdam Central Station, Hoog Hage in The Hague and the station area in Utrecht. The cities also wish to tackle their individual social and cultural problems more efficiently. The G4 will be opening a joint lobby office in Brussels.
