Research On Geo-strategic Of The Sino-USA-Iran Vital Triangle In The Early 21st Century

International political, economic and geopolitical structure changes at any time. Strategic interaction formed by global and regional triangle becomes to be the fulcrum of study on international relations and regional issues. The Sino-US-Iran relationship as a triangular relationship has a stable or disintegration effect on the Middle East, the Asia Pacific and the world politic.China, after 60 years of development, is growing into a big power in developing country, perseveringly and tireless efforts to adhere to the basic state policy of "reform and opening" and the firm pursuit of peaceful rise; Iran, through the Islamic Revolution and the Iran-Iraq war, after the Islamic way to go to rebuild, expand economy, export revolution, rise as a economic, political, military power in the Middle east, with the advance of the Gulf war, Afghanistan war and Iraq war US-lead; the USA, whose strength is in state of decay, but the world’s first powerful nation status can not be replaced in a short term. It was the three country far apart in the geographical space, be totally different in cultural traditions and social systems, has been producing and maintaining an extremely subtle and complicated important link because of national interest disputes, globalization and the coming of information society, forming a "enclave" geo-strategic "vital triangle" pattern, joining the world’s eastern Confucian civilization, the Islamic civilization in the Middle East, as well as the Western civilization represented by United States together, building up the Middle East forum, Asia Pacific plate, map of the world geopolitics pattern framework.This paper adopts the geopolitics, history, geography, economics, politics theories and methods to the study on geopolitics Pattern of the Sino-USA-Iran vital triangle in the early twenty-first Century; analysis of geographical location and geographic features of China, the USA, and Iran; analysis of the three bilateral (Sino-US, Sino-Iran, US-Iran) relations and bilateral strategic; analysis of the American factor in the Sino-Iran relationship, the Iran factor in the Sino-US relationship, the China factor in the US-Iran relationship. Then, Searches for the enclave geopolitical strategic triangle interaction theory and Practice on a global perspective. This paper argues that:national interest is the base and power formed the Sino-US-Iran vital triangle geo-strategy pattern; energy, nuclear issue is the actual power effected the reconstruction of the vital triangular pattern; either continuous or enclave strategic triangle, geopolitical factors in strategic triangle interaction will exist for a long time; civilization needs to seek common ground while reserving differences:China’s socialist system and the traditional "harmony", "the doctrine of the mean" philosophy, Iran’s theocratic system and Islamic fundamentalism, human rights and democracy of the United States under the cover of power-hegemony, is the three country’s respective characteristic, as well as the tool to establish and reinforce their respective status.This paper is made up of five parts:The first part the introduction, the main description of the research background and significance, research methods and innovation, research content and way of thinking, research focus and difficulty; and literature review.The second part, analysis of the US-Iran relationship and it’s China factors. Focus on the analysis of the US-Iran relationship’s realistic performance, characteristics, problems and essence, and strategic choice in bilateral relations; in-depth analysis of China’s geographical significance for the USA and Iran, and China’s impact on the US-Iran relationship.The third part, analysis of the Sino-Iran relationship and it’s America factors. Focus on the analysis of the Sino-Iran relationship’s realistic performance, characteristics, problems and essence, and strategic choice in bilateral relations; in-depth analysis of America’s geographical significance for China and Iran, and America’s impact on the Sino-Iran relationship.The fourth part, analysis of the Sino-US relationship and it’s Iran factors. Focus on the analysis of the Sino-US relationship’s realistic performance, characteristics, problems and essence, and strategic choice in bilateral relations; in-depth analysis of Iran’s geographical significance for China and the USA, and Iran’s impact on the Sino-US relationship. The fifth part, on the basis of the above analysis, to explore the "enclave geopolitical strategic triangle interaction" theory and Practice on a global perspective.The main innovation of this paper lies in:it is the first try to attempt to study Sino-US-Iran relationship based on the "enclave" triangle geopolitical strategy theory.The deficiencies of this paper may lies in:first, geopolitical strategy is a comprehensive discipline, demand in information screening and application is very high, the data is insufficient ability to grasp. Second, because of limited knowledge, the first empirical research on the triangular relationship based on the "enclave" triangle geopolitical strategy theory, is just a kind of courage and try. Third, take use of the traditional qualitative research method may lead to a stronger subjectivity. In fourth, the Sino-US-Iran vital triangle pattern is somewhat perplexing, together with the world pattern and international relations changes in every hour and moment, this discuss about the Sino-US-Iran geo-strategic triangle’s mechanism is still at the primary stage.
