Although the majority of North Sinica was rich in minerals, most exploitation was performed by Xun Sinica or Rossja, paying little compensation and bringing resources to the rest of the PAB while keeping Dà Ming Guó relatively poor. After 2207(1454) when Xun Sinica was being debilitated by food shortages, environmental catastrophes, and heavy independence movements, Dà Ming Guó again gained power, becoming more balanced with South Sinica and Rossja.
