Following the entrance ofChina into the WTO, the position of 'green barrier' becomes significantly important in the trade oftextile products. As China is a big country of textile production, speeding up the research onstandards for products of ecological textile, countering the latest situation appearing ininternational trade of textile, to take as quickly as possible responsive measures is a very urgentproblem in port, to enhancing the ability of international market competition and to promoting thestable development of foreign oriented economy.展开更多

In thewake of the current reform drive and "open-door" policy, the Loess Plateau has seen a burgeoning development in the regional economy that is now driven by a new momentum. Viewed from the increase of its grain output, exploitation of the land resources and fruit production, establishment of energy bases, soil-and-water conservation and other aspects, this article delineates a brand-new and panoramic blueprint for the Plateau’s future. So a new status in the development of China’s national economy is endowed to the Plateau.展开更多
