On the right track

US President Barack Obama walked down the gangway in Shanghai last night to begin his visit to China, which lasts through Wednesday.

Obviously, he is carrying with him a heavier agenda than his seven predecessors, with his hallmark appeal for "change". But he has arrived with many more positive notes from both sides, despite the differences and challenges that both countries face in their relations.

Obama has arrived better prepared, as both sides worked hard and ensured a smooth transition and a good start in the relationship after he moved into the White House in January.
