This summer, BusinessWeek brought together 13 of the smartest people we could find for an online roundtable on the past, present, and future of China and India (see below for a list of participants). On each of eight days, we posted a new question. Economics Editor Peter Coy moderated the discussion. The experts communicated both with us and with each other on everything from geopolitics to generation gaps. Now we’re sharing the discussion with you — and invite you to offer your comments.
