Internet service is another vital foundation for the diffusion of E-commerce. In China, Internet service is categorized as a value-added service that is open to domestic players. However, China's policy has divided its Internet service operators into two categories: Interconnecting Networks (INs) and Access Networks (ANs). The interconnecting networks are directly linked to the global Internet through international leased lines. So far, only eight IN licenses have been granted to the two academic networks, CERNET and CSTNet, and the six commercial networks, ChinaNET, ChinaGBN, UNINET, CNCnet, CIETNET, and CMNET.
