Chapter six, the conclusion of this paper, brings out some suggestions for future thinking about foreign strategy toward China. After the 1949 civil war in China, the Government reined by Kuomintang withdrew to Taiwan and the Communist Party of China won the political power of China. It has been 60 years since the People¡¦s Republic of China was established on October 1st 1949. All of the 4 successive leaders claimed that there is only on China in the world, and Taiwan is part of China. Therefore, there were Mao Zedong¡¦s force liberation to peaceful liberation, Deng Xiaoping¡¦s peaceful liberation to ¡§one country with two systems,¡¨ Jiang Zemin¡¦s continuous ¡§one country two systems¡¨ based on Hong Kong experience, and Hu Jintao¡¦s two-side strategy ¡X ¡§milder for the milds, and firmer for the firms¡¨ and ¡§One country two systems for peaceful union.¡¨ Based on the above-mentioned background, this study compared the successive 4 leaders¡¦ breeding, learning, personalities, statecraft, leadership, value of life, and the policy on Taiwan collection and analysis of papers, periodicals, dissertations, scholars¡¦ writings, governmental publication, statistics, researches, records issued in China, and foreign periodicals, dissertations, and writings. Hopefully, the results were expected to be helpful to reveal China¡¦s strategies for Taiwan by describing in detail about the origins, historical causes, and possible future development between Taiwan and China. The final goal is helping China and Taiwan to understand each other more deeply and to have more friendly interactions, thus there would be more opportunities for the two parities to cooperate and benefit both sides.
