BEIJING (Reuters) - China and the United States stressed the positives in their complex relationship on Friday during meetings between U.S. National Security Adviser Susan Rice and Chinese officials ahead of a U.S. visit by Chinese President Xi Jinping next month.

While the world's two largest economies have important mutual interests, like trying to rein in North Korea's nuclear programme, deep disagreements exist over everything from Internet security to China's claims in the South China Sea.
