The diplomatic rivalry between two sides of the Taiwan Strait originated from their disputes on the subject of China's sovereignty and their inducing reactions in the international community. Therefore, the consensus between them is necessary, if they want to settle these disputes to attain the diplomatic truce. Although both sides insist their legitimacy on representing the "de jure sovereignty of China", they must recognize the fact that there are two entities on Chinese territory under their different effective jurisdiction (e.g. de facto sovereignty). Accordingly, under the reality of "one China, two equal political entities", they may pursue the goal of national unity. In the meantime, under "one China policy", two complete international legal persons must be recognized through the "parallel recognition" by the members of international society. It must be done the same through the "parallel representation" in all international organizations. In fact, the ROC government has recognized Peking regime having its jurisdiction over the Chinese mainland and has declared no intention to challenge Chinese communist's international status. Thanks to the soaring call for independence by a lots of independentists and the misunderstanding of "pragmatic diplomacy" by Chinese communist, the ROC government should stress its adherence to the China's unification policy and do its best to dispel the opposing views of independentists. As to Chinese communist, it must revise its "one country, two systems" policy and its "use of force" attitude vis-a-vis Taiwan. The experience of German reunification has taught us that the only way to promote the aim of China's unification is through peaceful negotiation to abandon hostile treating gesture. The unique path for two sides to proceed to negotiations is firstly to attain the diplomatic truce. Because of Chinese communist' stubborn traditional ideas of sovereignty and its inflexible Taiwan policy, our proposals can be viewed only as unilateral aspiration.
