Hu's U.S. visit sets new tone but tensions remain

CHICAGO (Reuters) - Chinese President Hu Jintao headed home on Friday after a U.S. visit both sides declared a success, but which left questions over how the world's top two economic powers will manage future frictions.

Hu's visit, described by analysts as the most important U.S.-China meeting in 30 years, hit the right diplomatic notes with the pomp of a White House summit, pledges of greater cooperation and $45 billion in new business deals.
