	The BEPC (Beijing Electron Positron Collider) is being upgraded as a double-ring factory-like collider (BEPCII). A New and compact interaction region (IR) has been designed to afford a peak luminosity of 10e33 cm-2s-1 with an equal beam energy of 1.89 GeV, a cross angle of +/-11 mrad, 93 bunches and maximum beam current of 0.91 A. All the components of the IR have been fabricated successfully. During the commissioning of BEPCII the operation experience shows that the IR components have excellent performance and meet the design requirements. The design and realization of the interaction region for the BEPCII will be introduced in detail.
