INTERNATIONAL: "U.S. Objects to China's Web Filtering," By SAUL HANSELL, New York Times, June 25, 2009.

Ron Kirk, US Trade Rep, put it well:

"Protecting children from inappropriate content is a legitimate objective, but this is an inappropriate means and is likely to have a broader scope," Mr. Kirk said in the statement. "Mandating technically flawed Green Dam software and denying manufacturers and consumers freedom to select filtering software is an unnecessary and unjustified means to achieve that objective."

The six weeks notice also seems suspect, like a business/protectionist ploy.
