Knowing the government of China, I think a conspiracy exists to make the people think that there is no danger of radiation from Japan. I don't know that any clouds of radiation will reach China, but reports are that there is radiation in the ocean, which China shares with Japan. The Chinese government does not want panic. This could very well be a coverup on their part.
I have to admit that it was a surprise to see the label "rumormonger" under the picture of the man who was arrested. It makes me wonder what other things a person in China could be arrested for saying. And this is precisely why their government blocks many internet sites, including my blog! :)
Now go check out what the other consortium members have to say about this issue!
