This e-book gives an overview of the research work carried out within the framework of the MEDIUM project. Entitled “New pathways for sustainable urban development in China’s medium-sized cities », the MEDIUM project was funded by the European Commission under EuropeAid program, and run for three years (09/2015—08/2018). Its main objective was to train European young researchers in the knowledge of urban China and to foster Sino-European scientific cooperation on urban development. Various means have been deployed to this end, including medium-term mobility schemes to conduct research in China, and by co-organizing a series of scientific events with Chinese universities. Beyond scientific cooperation, the project has developed a pilot experiment: training Chinese students (or university students) to lead stakeholder workshops applied to urban planning, with a view to organizing consultations involving users of a targeted urban area.
