"China and Singapore are pooling expertise and finance to build a green urban community in north-east China, with the capacity for 350,000 people, near the western shore of the Bohai, one of the most polluted seas in the world.

At a ceremony to mark the start of construction on the first phase of Tianjin – an "eco-business park" over 150 hectares (370 acres) – investors said the 10-year scheme was intended to be "scalable and replicable" so it could be used across China, India and other developing nations."
