The position of the PRC is that the ROC and PRC are two different factions in the Chinese Civil War, which never legally ended. Therefore, the PRC claims that both factions belong to the same sovereign country—China. Since, as per the PRC, Taiwan's sovereignty belongs to China, the PRC's government and supporters believe that the secession of Taiwan should be agreed upon by all 1.3 billion Chinese citizens instead of just the 23 million residents of Taiwan. Furthermore, the position of PRC is that UN General Assembly Resolution 2758, which states "Recognizing that the representatives of the Government of the People's Republic of China are the only lawful representatives of China to the United Nations", means that the PRC is recognized as having the sovereignty of all of China, including Taiwan. Therefore, the PRC believes that it is within its legal rights to extend its jurisdiction to Taiwan by military means if at all necessary.
