In 1945, the ROC took control of Formosa (Taiwan), the Pescadores (Penghu) and other nearby islands, under the direction of the Supreme Commander for the Allied Powers. In September 1952, Japan officially renounced its right to Taiwan in the Treaty of San Francisco without explicitly stating the sovereignty status of Taiwan, and hence some people believe that the sovereignty of Taiwan is still undetermined.
In addition, the situation can be confusing because of the different parties and the effort by many groups to deal with the controversy through a policy of deliberate ambiguity. The political solution that is accepted by many of the current groups is the perspective of the status quo: to unofficially treat Taiwan as a state and at a minimum, to officially declare no support for the government of this state making a formal declaration of independence.
