China may well become the world’s largest economy, but because its policies have exhibited such fear of the Internet, it “can’t lead a knowledge-based revolution,” former Secretary of State Condoleezza Rice told CNBC Wednesday.

“China has a political system that’s quite rigid,” added Rice, who was secretary of state under President George W. Bush and an advisor and confidante in his father’s administration. Rice, who has just published a book about her parents called Extraordinary, Ordinary People: A Memoir of Family, is a professor of political economy at the Stanford Graduate School of Business.
