China Is Said to Use Powerful New Weapon to Censor Internet - NYTimes.com

Behold "the Great Cannon"

"China’s new Internet weapon, the report says, is similar to one developed and used by the National Security Agency and its British counterpart, GCHQ, a system outlined in classified documents leaked by Edward J. Snowden, the former United States intelligence contractor. The American system, according to the documents, which were published by The Intercept, can deploy a system of programs that can intercept web traffic on a mass scale and redirect it to a site of their choosing. The N.S.A. and its partners appear to use the programs for targeted surveillance, whereas China appears to use the Great Cannon for an aggressive form of censorship.

The similarities of the programs may put American officials on awkward footing, the researchers argue in their report. “This precedent will make it difficult for Western governments to credibly complain about others utilizing similar techniques,” they write."
