In just a few weeks, U.S. companies that do business in China are going to confront a host of challenges related to the enactment of a fresh batch of cybersecurity rules that could also force open the locks on trade secrets and other sensitive information.

Now, in light of the new, far-reaching rules, doing business in China is likely to be “more challenging and potentially perilous,” he said.
