    The Paleogene to Neogene Nan Xian sedimentary basin, which is typical of non-marine oil producing sedimentary basins in eastern China, is composed of four structural depressions called the Bi Yang Depression, Nan Yang Depression, Xiang Yang Depression, and Shuang Gou Depression, respectively. The northern Bi Yang and Nan Yang Depressions are the major oil fields in Nan Xiang sedimentary basin, where 3×109 ton of crude oil has been produced during the 40 years since the start of petroleum exploration in the 1950's. Nan Xian crudes are generally characterized by high wax contents (30 to 50%), high pour points (40 to 50°C), and low sulphur contents (0.05 to 0.14%), suggesting that the crude oils are derived from biodegraded higher plants. Some biomarkers such as steranes and hopanes in crude oils, however, suggest significant contribution of zoo- and phytoplanktons.
    Oil/source rock correlations by biomarkers showed that black shales of middle Paleogene He Tao Yuan Formation are major source rocks in Nan Xiang sedimentary basin. The He Tao Yuan Formation is characterized by a sequence of fluvial alluvial, delta front, and deep basin facies in lacustrine depositional environment. The He Tao Yuan black shale was formed by turbidity current deposition in a deep lake basin when great amounts of river borne clastic sediments accumulated during the marked subsidence of the basement. The He Tao Yuan black shales were enriched in organic matter (present average total organic carbon content=1.8%) because of the increased primary production due to temperate climate and the anoxic depositional environment in the deep basin center. The kerogen of the He Tao Yuan black shale is characterized by oil prone Type I and Type I-II kerogens. The Bi Yang Depression and a part of Nan Yang Depression, especially, could possess the most favorable depositional condition for the formation of petroleum source rocks among others. Several reservoir structures were formed during the uplift of basement during late Paleogene to early Neogene time. Reservoir rocks are mainly sans nes of He Tao Yuan Formation deposited in fluvial and alluvial planes, and delta front in Nan Xiang paleo-lake. He Tao Yuan source rocks have been maturated enough to produce hydrocarbons with the re-subsidence of basement in Neogene Tertiary time. Lithofacies of turbidite alternation was advantageous for the effective expulsion and secondary migration of petroleum hydrocarbons. Much of the hydrocarbons generated have been efficiently accumulated into previously formed traps of the same stratigraphic horizon to form petroleum deposits. The Bi Yang and Nan Yang Depressions have mainly produced liquid oils with a little gas of biodegraded origin. In addition to shallow reservoir depth and oil prone kerogen types of source rocks, the low gas/oil ratio in Bi Yang and Nan Yang oil fields is mainly due to that the He Tao Yuan source rocks have not been overmatured to generate thermocatalytic gases through the evolution history of Nan Xian sedimentary basin.

    Official Chinese Communist Party history simply indicates that Deng Xiaoping launched the open-door policy in 1978, largely discounting international factors, such as China’s joining the United Nations and China-U.S. reconciliation. With regards to the pre-1978 era, most studies focused on inter-Politburo politics, because during the Cultural Revolution power struggles often occurred among the leadership. According to the literature, the political situation after the death of Lin Biao is described as the struggle between Zhou Enlai, who aimed at economic reconstruction, and the radicals such as the “Gang of Four,” but they were under the almost complete dominance of Mao Zedong. Previous studies describe how Zhou’s economic policy was at the mercy of politics, and do not analyze his intention and policy. This article reconsiders the conception and limitation of the open-door policy which was launched as a part of Zhou’s policy, considering the importance of the changing international circumstances through analyzing a project designed to import large industrial plants from Western countries. This project was called the “4-3” development strategy, because its total projected cost was US$4.3 billion.
    Closer examination reveals that the industrial development strategy underlying the open-door policy was formed gradually in the early 1970s, in association with the change in the leadership’s perception towards new international circumstances. Until then, the Chinese leadership had pursued the construction of “the third front” as a preparation for war, which was a massive construction of defense and heavy industries in inland China. However, the change in the international situation in the early 1970s reduced the necessity of preparing for a war. Zhou Enlai and the bureaucrats therefore proceeded with the “4-3” development strategy as a part of a new national strategy, which included the reorganization of the bureaucracy to support the open-door policy and the shift of investment from military industry to agriculture and light industry and from inland to coastal areas. They implemented these policies through modifications of the 4th Five Year Plan.
    However, there was a conflict between the open-door policy and Mao’s revolutionary diplomatic strategies, despite Mao’s support for the former. The conflict came to the surface as the U.S.-Soviet détente emerged, and the pursuit of the opening was hampered. However, the open-door policy was gradually transformed into a comprehensive industrial policy. As a result, Hua Guofeng and Deng Xiaoping were able to launch a systematic open-door policy soon after Mao’s death.

    This article aims to re-examine the political process that allowed Deng Xiaoping to regain his power as Chinese leader in 1978, by focusing his foreign policy on domestic politics. Theoretical relations between his modernization strategy, foreign policy and the international state of affairs will be analyzed. It will be shown how Deng increased the tension with Soviet and Vietnamese “hegemons” while strengthening relations with Western capitalists and South-Eastern Asiancountries. His actions led him to become bogged down in the Sino-Vietnamese War in February1979. In doing so, the earliest foreign policy of Deng, who later became a leading advocate of the “independent foreign policy” as China opened up, will be clearly demonstrated.
    In foreign policy terms, Deng was an orthodox successor to Mao Zedong and highlighted opposition to Soviet “hegemonism.” However, Deng’s greatest domestic political vulnerability arose from his personal history. Deng had been criticized by Mao for his ambitious domestic policy which contradicted Mao’s revolutionary zeal. The United States presidential advisor Zbigniew Brzezinski visited China in May 1978 and stressed the importance of Sino-US strategic cooperation. Brzezinski offered China several technical measures to facilitate such relations.After their meeting, Deng started to promote his new opening-up strategy: because Mao’s diplomacy to form a coalition with the world against the Soviets had been successful, and also because the Soviet Union was actually perceived as the biggest threat to the world, the US and its allies were willing to help China to become strong enough to deter the powerful Soviet Union.Although the world situation was at a difficult stage, a precious opportunity for China to rapidly develop its economy had arrived with help from the developed countries.
    After winning many diplomatic successes with those nations, Deng justified his hurried development strategy by utilizing Mao’s foreign policy within the Chinese Communist Party(CCP). He proposed that the party should transfer its focus from class struggle to economic development, and gradually consolidated his domestic power. In parallel, China increasingly exaggerated the Soviet threat and its“ surrogate” Vietnamese threat. As the situation in Indochina worsened, Deng made his final decision to launch a war against Vietnam immediately after he took over the leadership of the CCP in late November 1978.
    In addition to referring to newspaper articles and information in previous studies, this subject uses a volume of historical documents and memoirs published in China in recent years, as wellas diplomatic records relating to China from other countries.
