The Border Trade between border provinces of Mainland China and their neighboring countries is a unique form of economy and trade. Before the reform and opening up in 1978, due to political, diplomatic, secure and planned economic considerations, the border trade had been rather limited. After the reform and opening, PRC began to reform foreign trade regime and to execute decentralization. Provinces scrambled developing foreign trade to prosper local economy. Border provinces, geographically in disadvantage, relied on border trade as a means of boosting economy, which has been featured in the model of foreign trade. Meanwhile, in order to take care of the ethnic minority in border provinces, the government has applied preferential rules successively to help promote border trade. Since the 1980¡¦s, accompanied with the improvements of relation between the PRC and its neighboring countries, Mainland China began to pay attention to the development of border trade. The Guangxi¡¦s ethnic minority lives in a gathered community. Owing to poor natural circumstances and long-term fighting, it has become one of the economically laggard provinces of border. Guangxi borders on Vietnam. Bilateral border trade has a long history, though it had been interrupted for a certain time due to strategic status and deterioration of China-Vietnam relationship. Until the relationship was normalized in the end of 1991, the border trade between both sides reached a new stage. While the PRC carries out an open-door system for border and has endowed with border trade preferential policies since 1992, Vietnam also executes opening the market and reforming economic policies. In consequence, the amount of Guangxi-Vietnam¡¦s border trade has been growing fast; border trade carries a heavy weight in foreign trade. Border trades make effects on promoting the living standard, increasing the income of frontiers, escalating local government¡¦s revenue, improving local construction, adjusting industrial structure, attracting foreign investment, strengthening local economic capability, benefiting the frontier steadiness and people united, as well as expanding good relationship with neighboring-countries. Obviously, border trades have made a significant meaning and contribution in economic development. Recently, it became a trend for countries and regions all over the world to carry out a closer economic cooperation on free trade, and form a regional economic group. Appropriate method to develop Guangxi¡¦s border trade is to furthermore become involved in the framework of economic regionalization of the neighboring-countries, to enlarge the magnitude of foreign-trade and to strengthen economic and trade cooperation with the Association of Southeast Asian Nations.
