The Zhejiang Government established XiXi Sci-Tech Island in December 2008 to develop the Yu Hang district as a technology hub. Alibaba became the first major tenant in July 2009. XiXi covers 99 square kilometers and aims to incubate companies, share resources, and build business networks. It will include residential and commercial areas, a university town, parks, and recreational facilities. Transportation infrastructure like metro lines and highways are being expanded to connect XiXi to surrounding cities.
