The area supplied by a monopoly public enterprise operated by a local government shall be limited to the area under that government's jurisdiction, provided that a stipulation to expand the area supplied may be made by agreement with the local government of a neighboring area.

The central government, in order to increase national treasury revenues or to control the costs of production, may sell monopoly goods in accordance with the provisions of law, and may manufacture such goods.
