Frequently Asked Questions
Google withdrew its search service from mainland China in 2010, citing censorship requirements and cyber attacks. The company redirected google.cn to google.com.hk (Hong Kong). Since then, Google's services including Search, Gmail, YouTube, and Google Maps have been largely inaccessible from mainland China without VPN. The Chinese government maintains the Great Firewall to filter internet content according to its regulatory framework. Google's departure created the vacuum that Baidu filled, eventually dominating the Chinese search market. While Google has occasionally expressed interest in re-entering China (most notably with the Dragonfly project in 2018), each attempt has faced significant internal and external opposition and has not resulted in a relaunch of Google Search in mainland China.
AI is fundamentally reshaping search in China through several key developments: conversational search has replaced keyword-based queries for complex information needs, with users increasingly asking full questions in natural language; AI-generated summaries at the top of search results (similar to Google's AI Overviews) now appear for 40% of queries on Baidu; new AI-native search engines like Kimi Search (from Moonshot AI) and Doubao Search (from ByteDance) offer direct answers rather than lists of links, reducing the need for users to click through to websites; Baidu's ERNIE Bot has been integrated directly into search, providing personalized answers and follow-up conversations; and voice search has surged, with 30% of mobile searches now conducted via voice. The shift toward AI search mirrors global trends but is progressing faster in China due to the absence of Google and the aggressive investment by Chinese tech companies in AI capabilities.
