China and Singapore will build an "eco-city" in Tianjin using a new joint venture between firms from both countries, with Singapore's Keppel Corporation playing a lead role, AFP reported. The project will use advanced energy-saving and environmental technologies in hopes of turning Tianjin into a model "green" city. Singapore government officials said the project's management, technology, and policy aspects will serve as a reference for other Chinese cities. The announcement was made during Prime Minister Wen Jiabao's five-day visit to Singapore, the first visit by a Chinese premier in eight years. Bilateral trade between China and Singapore totaled US$59 billion last year, up from US$44 billion in 2005.
