Shanghai’s Hongqiao area will be transformed into an “international central business district and trading center” to serve the national strategy of "integrated development of the Yangtze River Delta Region." The other areas in the strategy are the new section of the China (Shanghai) Pilot Free Trade Zone and an “ecological green development demonstration zone” in Wujiang in neighboring Jiangsu Province, Jiashan in Zhejiang Province and the Qingpu District in Shanghai. “Integration and high quality are the keywords for Shanghai, which will play a lead role in the Yangtze River Delta integration,” Shanghai Mayor Ying Yong said at a press conference of the State Council Information Office in Beijing on Tuesday.
