"It (President Xi Jinping's speech on video to the Wuzhen internet conference) is very instructive. It shows that Chinese leaders have all the principles in place, now they need to execute. China has connected half of its population (to the internet). How it will connect the other half - that's the main challenge."

Raj Reddy, professor of computer science and robotics, Carnegie Mellon University, Pittsburgh, US

"It's a very good speech and his aspiration is also our aspiration."
