Tianjin Eco-city: Gloria Ng, who leads Service Innovation Practice, at the Institute for Systems Science at NUS Singapore told me about the Tianjin Eco-city collaboration between Singapore and China:  “We aim to build an economically thriving, environmentally friendly, socially harmonious and resource-efficient city. The key concept underpinning the planning and development of the Sino-Singapore Tianjin Eco-city is the “three harmonies” – man living in harmony with man, now and for future generations; man living in harmony with economic activities; and man living in harmony with the environment.” http://www.tianjinecocity.gov.sg/    She also mentioned that Singapore recently hosted the World Cities Summit:   http://www.worldcities.com.sg/
