O'Neill also said the fast pace of China's economic expansion, which he noted puts it on course to double the size of the economy over the coming decade, is not a threat to the US. When asked whether China's economic development presents a danger to its Asian neighbors or to the US, the Treasury Secretary said: "I think there's nothing to fear at all in economic progress in every part of the world." He emphasised his belief that development is not a zero-sum game, stating: "I don't understand those who fear economic progress for everyone, everywhere, as fast as we can produce it."
