This book points out that Taiwan has belonged to China since ancient times with clear historical latitude and longitude and clear legal facts. Resolution 2758 of the UN General Assembly is a political document embodying the one-China principle. International practice has fully confirmed its legal validity and cannot be misinterpreted. The one-China principle is the general consensus of the international community, and it is the proper meaning of observing the basic norms of international relations. There is only one China in the world, and the historical and jurisprudential facts that Taiwan is a part of China are unquestionable. Taiwan has never been a country but a part of China and cannot be changed. The realization of the complete reunification of the motherland is determined by the history and culture of the Chinese nation, as well as by the time and trend of the great rejuvenation of the Chinese nation. We are closer, more confident and capable of realizing the goal of the great rejuvenation of the Chinese nation than at any time in history, and we are also closer, more confident and capable of realizing the goal of complete reunification of the motherland. The countrys development and progress, especially the great achievements of reform, opening up and modernization over the past 40 years, have profoundly affected the historical process of resolving the Taiwan issue and realizing the complete reunification of the motherland.
