Beijing has postponed the deadline for the mandatory installation of internet filtering software known as "Green Dam," the South China Morning Post reported, citing state media. The Ministry of Industry and Information Technology (MIIT) said the delay was due to some computer manufacturers saying they needed more time to install the software on their machines. Chambers of commerce and trade groups in the technology sector have called on Beijing to scrap the requirement that all new PCs sold in China come with the software pre-installed. MIIT says the software is aimed at protecting youth from pornography and violence, and says it received good feedback from internet cafes and schools where the software was installed. Green Dam was installed on 2.62 million computer terminals in schools and 4.7 million terminals in internet bars by the end of May, according to the ministry. Some critics of the project see the delay as a victory for free speech while others see it as a face-saving measure by Beijing.
