Ximending area). The redevelopment hoped to increase the prosperity of the eastern district and the convenience of urban life for existing residents. The center's purpose was to expand business investment in the area and attract international financial services and technology firms. It also planned for residential development by building a completely new community. The Xinyi Project Area is the only commercial development area in Taipei with a wholly planned street and urban design. In addition to attracting corporations, it also features large retail spaces, department stores, and shopping malls. Xinyi Special District is now the prime central business district of Taipei.
