Shanghai is a major shipping hub in eastern China, ranking third in the world by container throughput for the last 4 years. The Port of Shanghai handled 2.27 million containers in 2007, up 2 percent from 2006. China is exporting vast numbers of containers, representing a growing opportunity for potential terrorist attacks. In June 2007, the Shanghai International Port Group (SIPG), the Georgia Ports Authority (GPA) and Savi Networks announced plans to launch a network based on Radio Frequency Identification (RFID), called the Shanghai-Savannah Express Trade Lane. The project entails tracking the movement of containers to ensure they have not been tampered with en route before or after scanning. The end goal of the project is to develop a working model of what U.S. Customs calls a “green lane”, a supply chain that is fast-traced due to its known security. Having a green lane would give certain customers the ability to move their containers as efficiently and securely as possible.
