The regional and community governments have jurisdiction over transportation, public works, water policy, cultural matters, education, public health, environment, housing, zoning, economic and industrial policy, agriculture, foreign trade, and oversight of provincial and local governments. They rely on a system of revenue sharing with the federal government for most of their funds. They have the authority to levy taxes (mostly surcharges) and contract loans. Moreover, they have obtained treaty-making power for those issues coming under their respective jurisdictions.

Of total public spending--interest payments not considered--more than 40% is authorized by the regions and communities.
