The transnational financial markets, the fluctuations of oil, gas or food prices and the constraints of a multi-polar geopolitical order exert an impact on their economies, but do not command their policies. In a globalizing world, they act while the others react.展开更多

David Gosset of the Shanghai-based China Europe International Business School analyzes "a new world with Chinese characteristics." He also points out that Westerners should reflect on their prejudices about China and "look at China as a living matrix of a civilization that is already shaping our time." His main ideas follow:展开更多
