The Republic of China (ROC), commonly known as Taiwan, currently governs the Taiwan Area, consisting of the four main archipelagos of Taiwan, Penghu, Kinmen, Matsu and some minor islands. The area under control of the Republic of China is divided into two streamlined provinces (Taiwan Province and Fujian Province) and six special municipalities (Kaohsiung, New Taipei, Taichung, Tainan, Taipei and Taoyuan). The two streamlined provinces are further subdivided into 3 provincial cities and 13 counties. All special municipalities, provincial cities and counties are directly under the central government (i.e., Executive Yuan). The Government of the Republic of China also constitutionally claims mainland China on a historical basis.
