Google is opening an artificial intelligence center in China

"The science of AI has no borders, neither do its benefits," Fei-Fei Li, chief scientist at Google's AI business, said in a blog post Wednesday announcing the new center. But China's internet borders are fortified by the so-called Great Firewall, and most of Google's biggest products -- its search engine, YouTube and Gmail -- have been blocked by the country's vast censorship apparatus for years. Google (GOOGL) effectively left China in 2010, but the country's 730 million internet users make it too large a market to ignore. The company has made no secret of its desire to find ways to rebuild its presence there.
