SHANGHAI - Chicago Mayor Richard M. Daley promoted his native "Windy City" to China's clean-energy companies and signed an Eco-City Partnership agreement with his Shanghai counterpart Han Zheng during the first leg of his Asian visit this week.

Daley, who will step down in May after over 21 years in office, said he wants to spend his remaining time building Chicago into one of the world's most environmentally-friendly cities to further attract tourists and trade, with an eye on China.

On Monday, he met with CEOs from Chinese companies and spoke at a luncheon hosted by the American Chamber of Commerce in Shanghai.
