To achieve the mission, Baidu will strengthen its mobile foundation in AI and use AI as a fundamental driver to elevate its current core business, specifically core products of Mobile Baidu, search and feed,according to Robin Li, Baidu's Chairman and Chief Executive Officer.

Meanwhile, Baidu will continue to build out its newer AI-enabled initiatives through an open platform and ecosystem approach to capture long-term economic opportunity, Li added.
