The newest Oriental bureau in-charge of censorship and Web control might have recently revealed a stirring tv anthem observing its formation of cyber-space, but international businesspeople here say they have little to sing about.

They’re increasingly frustrated by the growing obstacles to access to the internet that is extensive, such as the burdensome system of censorship called the Great Firewall, based on study results released this week by the Eu Chamber of Commerce in China.

106 firms that are located in Europe and also have offices in China answered the survey. Eighty-six percent of the participants said their companies had been negatively influenced by the blocking of certain sites or tools. That was an increase from 71 percent in last year’s study.

After preventing Gmail downloads through these programs, inducing more individuals to turn to VPN software, the authorities continued to vigorously assault V.P.N.’s .

The chamber had not been amenable to set up these functions here, because limitations increased at the start of the year, or discovered that 13 per cent of study participants had recently deferred investment more in research and development in China. Many information about VPN is also provided by the German website of VPN Test.

“These worrying trends exemplify how extreme securing of Web controls may choke company growth and stop investing in technology and R&D — areas which are vital for China’s advancement,” Jorg Wuttke, president of the chamber, said in a statement Thursday. “This is worsened by the fact that these measures are also deterring much-needed international gift.
