Seattle is under tight security for the first official visit to the United States by China's President Xi Jinping. Xi arrived today, but he won't get his 21-gun salute at the White House until Friday. His meeting tomorrow with the elite leaders of America's tech industry may be just as important. With the world's biggest Internet market at stake, Microsoft, Apple, Amazon and others may need China more than China needs them. Can they demand that China protect their intellectual property rights, or can China make censorship and Cyber-attacks the cost of doing business? And, what's the role of the Obama Administration, which has warned of possible sanctions over theft of trade secrets?
