Baidu Inc. /zigman2/quotes/209050136/composite BIDU +0.22% said Thursday has suspended updating content on certain newsfeed channels within Baidu App and conduct maintenance, starting April 8, following directives from government regulators. The China-based internet search giant said the suspension could have an impact on marketing services revenue. The move follows reports that China's cyberspace regulator said some of Baidu's reviews of news feed channels weren't strict, and therefore had a bad influence on society. Baidu said other measures it's taking to comply with regulator directives include monitoring and management over its platform, strengthening the integrity and quality of content and improving business practices.
