Architects Planners of SITE France and SITE Asia have published many articles in Vietnamese architectural magazines on urban planning and particularly about the ''Great Hanoi” where they expressed their ideas. Within CCIFV, SITE has organized two symposia about the topic in 2009 & 2010 with the Vice-Ministers of construction and official managers for urban planning. Their hope is to see Hanoi become an example of urban success, a city unpolluted, well-landscaped and without ghetto where rich people, less wealthy and non-favored people will share the joy of life. This may happen if wisdom prevails over money, if urban planning laws prohibit the abuse of some property developers, if the green spaces multiply and make it a garden city, if the collective ecological transports can replace the pollutant transports, if the new quarters do not become dormitory towns, repeating the mistakes made in the 90s in the suburbs of Paris, as the famous Sarcelle.
