All contracts and agreements between public utilities as to rates shall be submitted to the Commission for inspection that it may be seen whether or not they are a violation of law or the rules and regulations of the Commission, and all arrangements and agreements whatever as to the division of earnings of any kind by competing public utilities shall be submitted to the Commission for inspection and approval insofar as they affect the rules and regulations made by the Commission to secure to all persons doing business with such utilities just and reasonable rates. The Commission may make such rules and regulations, as to such contracts and agreements as the public interest may require.
