Upon Japan renouncing rights and not specifying who it goes to, Taiwan either has to be considered to a) belong to the then-current administrators (the ROC), b) be abandoned in which case it goes to the ROC under the same principle as squatters rights or c) be returned to the former owners (Qing which was succeeded by the ROC).
