A portion of Facebook Inc. Chief Executive Mark Zuckerberg’s opening statement for Wednesday’s Big Tech hearing on antitrust issues is out. “I believe it’s important to maintain the core values of openness and fairness that have made America’s digital economy a force for empowerment and opportunity here [in the U.S.] and around the world,” Zuckerberg says, according to a tweet from CNN reporter Donie O’Sullivan. Zuckerberg and the CEOs of Apple Inc. , Amazon.com Inc. , and Google parent Alphabet Inc. are scheduled to make roughly five-minute remarks at the beginning of the House hearing, which will delve into their business practices and immense economic influence. Zuckerberg’s statement, which references the rise of competition from China, could frame an underlying argument that in weakening Facebook with strict rules, the U.S. government could unwillingly strength the Chinese economy. Facebook was not immediately available for comment.
