When China's prime minister, Wen Jiabao arrives here on Saturday, his four-day visit will be filled with the usual handshakes and protocols(礼仪) that would ordinarily go little noticed beyond this region. This diplomatic mission, though, will have an altogether different feeling. Perhaps for the first time, there is an expectation that both India and China, together representing a third of humanity, are coming into their own age at the same moment, with the potential for a great shift in the world's politics and economy. The impact on the global balance of power, the competition for resources and the health of the planet is causing many analysts and political leaders to sit up and take notice. For the rest of the world, this shift could be profound. For industrialized nations in the years ahead, it may well mean more downward pressure on wages, the loss of still more jobs and greater competition for investment. In most countries it will likely lead to higher prices for scarce resources. The rise of China has already been felt far and wide, from the export of often unbeatably cheap manufactures to the thick smoke of its industrial pollution that spread eastward across the Pacific and the effect of its fast-growing economy on rising oil prices. The addition of India, already a major force in services, could pull the globe's economic and political center of gravity decidedly toward Asia, and away from an aging Europe and a United States which is already stretched by security threats and increasing deficits(赤字). Indeed, Beijing's overtures(主动姿态) toward India are being contemplated with a keen awareness of China's rivalry with the United States, which has also jealously courted(讨好) New Delhi, lately promising to help make it a 'major world power in the 21st century'. For that reason, Wen will come with a package initiatives(倡议). They are aimed at drawing India and China, the world's two most populous nations, closer than they have been at any time since the 1950s. Both sides say they will push hard to resolve a decade-old border dispute. There is the talk of a free-trade agreement as well as joint oil exploration and purchases of commercial airliners.
