SAN FRANCISCO — Mark Zuckerberg, Facebook’s chief executive, has cultivated relationships with China’s leaders, including President Xi Jinping. He has paid multiple visits to the country to meet its top internet executives. He has made an effort to learn Mandarin.
Inside Facebook, the work to enter China runs far deeper.
The social network has quietly developed software to suppress posts from appearing in people’s news feeds in specific geographic areas, according to three current and former Facebook employees, who asked for anonymity because the tool is confidential.
