From the Washington Post, the next installment in Philip Pan's Great Firewall of China Series (link):
A state-run newspaper reported Tuesday that Google Inc. is under investigation for operating without a proper license in China and quoted an unnamed government official as saying the Internet giant needs to cooperate further with the authorities in blocking "harmful information" from its search results.
The report, in the Beijing News, was published the same day that another state newspaper ran a harshly worded editorial about Google. The paper accused the firm of sneaking into China like an "uninvited guest" and then making a fuss about being required to follow Chinese law and cooperate in censoring search results such as pornography.
The unusually bold attacks in the state media suggest that the Chinese government is unhappy with Google's efforts thus far to filter politically sensitive results from its popular search engine in China, and that its ability to do business in the country may be in jeopardy.
