Linda Yueh: G20 delivers 'more and less' Leaders at the summit of the G20 group of nations delivered "more and less" than was expected, according to BBC chief business correspondent, Linda Yueh. She says that climate change and the Ebola crisis made it into the leaders' final statement, which was more than expected. But, leaders failed to say how they would go about boosting global growth, which was an omission according to our correspondent.
