The China-Singapore Tianjin Eco-City is a flagship bilateral project between the governments of China and Singapore. In April 2007, the leaders of China and Singapore proposed to work together to build an eco-city in China, amidst rapid urbanisation and greater emphasis on sustainable development across the world. On 18 November 2007, then-Chinese Premier Wen Jiabao and Then Singapore Prime Minister Lee Hsien Loong signed the framework agreement for both countries to jointly build the Sino-Singapore Tianjin Eco-City. Since then, the governments of both countries have cooperated closely to drive the development of the Eco-City, with the aim of consolidating the best ideas from both countries and internationally to transform what was once an saline-alkaline wasteland into a prosperous Eco-City, so as to achieve the common vision of building a city that is ecologically friendly, socially harmonious and economically sustainable. When completed, the 30 sq km Eco-City will be a modern sustainable city which can support 350,000 people. 

Since the groundbreaking ceremony in September 2008, leaders from China and Singapore have shown strong support for the Eco-City and made regular visits to oversee its progress and guide its development.
