Google stops censoring search results in China
Google has stopped censoring its search results in China, ignoring warnings by the country's authorities.
The US company said its Chinese users would be redirected to the uncensored pages of its Hong Kong website.
China's official Xinhua news agency said Google had violated a "written promise" and was "totally wrong" to end censorship of its Chinese-language search portal Google.cn.
Chinese government officials had warned Google repeatedly that it would face consequences if it did not comply with the country's censorship rules.
On Sunday, state media in China had attacked Google for what they described as the company's "intricate ties" with the US government.
Google provided US intelligence agencies with a record of its search engine results, the state-run news agency Xinhua said.
While Google is the world's most popular search engine, it is a distant number two in the Chinese market, which is dominated by Baidu.
However, because of the size and growth rate of China's internet population, any loss of business there is likely to harm Google's future growth prospects.
Analysts said that initially Google's prospects would not be dented by shutting down Google.cn as it is responsible, at most, for 2% of its annual $24bn (£15.9bn) revenue.
"Near-term, not that big a deal," said Tim Ghriskey, chief investment officer at Solaris Asset Management. "Long-term, if this stays in place, it's a negative. China is certainly a great growth opportunity."
It is well-known that China operates one of the most sophisticated and wide-reaching censorship systems in the world.
Thousands of police officers are employed to monitor web activity and many automated systems watch blogs, chat rooms and other sites to ensure that banned subjects, such as Tiananmen Square, are not discussed.
