Wall Street Journal reported that China's tightening grip on the internet has forced U.S. companies to recalibrate their efforts here, but there was little outward sign of friction as American executives on Sunday touted their commitment to the crucial Chinese market during the government's annual cyberspace conference. Apple Chief Executive Tim Cook and Cisco CEO Chuck Robbins were among those echoing the conference theme: "Developing [a] digital economy for openness and shared benefits." That theme "is a vision we at Apple share," Mr. Cook said. "We are proud to have worked alongside many of our partners in China to help build a community to join a common future in cyberspace." ... "In order to build this common future, we must also embark on a new area of global cooperation and new partnerships," Mr. Robbins said. "No one company, no one country can do it alone. "...As U.S. technology executives gather in Wuzhen,  U.S. President Donald Trump's trade team is considering actions against China for suspected trade violations, including alleged pressure by China on U.S. tech companies to turn over their intellectual property for access to the Chinese market. The executives might have decided to come in part to ease potential tensions that could jeopardize their businesses in China.

Reuters said that Chinese President Xi Jinping said on Sunday the country will not close its door to the global internet, but that cyber sovereignty is key in its vision of internet development. Xi's comments were read by Huang Kunming, head of the Chinese Communist Party's publicity department at the country's largest public cyber policy forum in the town of Wuzhen in eastern China. "The development of China's cyberspace is entering a fast lane...China's doors will only become more and more open," said Xi in the note. Cyber sovereignty is the idea that states should be permitted to manage and contain their own internet without external interference...China has advocated strongly for a larger role in global internet governance under Xi..."China stands ready to develop new rules and systems of internet governance to serve all parties and counteract current imbalances," said Wang Huning, a member of the Communist Party standing committee at the event on Sunday.
