The students and Chinese media have offered a handful of examples of what they say is bias among Western journalists.
One Web site, www.anti-cnn.com, complained that several news outlets showed photos of police in Nepal scuffling with protesters and misidentified the security forces as Chinese.
It accused US-based CNN of improperly cropping a photo of Chinese military vehicles on its Web site to remove Tibetan rioters who were pelting the trucks with rocks.
CNN insisted it has reported impartially.
"CNN refutes all allegations by bloggers that it distorts its coverage of the events in Tibet to portray either side in a more favorable light," the network said in a statement.
The photo of military vehicles "was used wholly appropriately," the statement said. It said there should be no confusion because the image was captioned, "Tibetans throw stones at army vehicles on a street in the capital Lhasa."
Yao, 22, is a Chinese-born computer engineering student at Canada's Simon Fraser University. He has lived in the US and Canada since age 10, but says his loyalties lie with China.
He plans to return after his graduation.
"We are under no government influence and we are doing this strictly because we believe that, we, as people who have Chinese heritage in us, should try to correct the world when they have been wrongly informed about China," he said in an e-mail.
