Cross-Strait relations
The ROC government has in the past actively pursued the claim as the sole legitimate government over mainland China and Taiwan. This position began to change in the early 1990s as democracy was introduced and new Taiwanese leaders were elected, changing to one that does not actively challenge the legitimacy of PRC rule over mainland China. Both the PRC and the ROC carry out Cross-Strait relations through specialized agencies (such as the Mainland Affairs Council of the ROC and the Taiwan Affairs Office of the PRC), rather than through foreign ministries. Different groups have different concepts of what the current formal political situation of Taiwan is.
