Kinmen , also known as Quemoy, is a small archipelago of several islands administered by the Republic of China (ROC): Greater Kinmen , Lesser Kinmen, and some islets. Administratively, it is Kinmen County of Fukien Province, Republic of China. The county is claimed as part of Fujian's Quanzhou Prefecture by the People's Republic of China (PRC). Some islands of other counties, such as Wuchiu, were transferred to the jurisdiction of Kinmen County by the ROC government following its civil war defeat and retreat to Taiwan. Matsu is the other set of islands on the Fujian coast controlled by the ROC.
