Article IV.
The Contracting Parties will use whatever influence they respectively exercise with any State, States, or Governments possessing, or claiming to possess, any jurisdiction or right over the territory which the said canal shall traverse, or which shall be near the waters applicable thereto, in order to induce such States or Governments to facilitate the construction of the said canal by every means in their power; and, furthermore, Great Britain and the United States agree to use their good offices, wherever or however it may be most expedient, in order to procure the establishment of two free ports, one at each end of the said canal.
Article V.
The Contracting Parties further engage that when the said canal shall have been completed, they will protect it from interruption, seizure, or unjust confiscation, and that they will guarantee the neutrality thereof, so that the said canal may for ever be open and free, and the capital invested therein secure. Nevertheless, the Governments of Great Britain and the United States, in according their protection to the construction of the said canal, and guaranteeing its neutrality and security when completed, always understand that this protection and guarantee are granted conditionally, and may be withdrawn by both Governments, or either Government, if both Governments, or either Government, should deem that the persons or company undertaking or managing the same adopt or establish such regulations concerning the traffic thereupon, as are contrary to the spirit and intention of this Convention; either by making unfair discriminations in favour of the commerce of one of the Contracting Parties over the commerce of the other, or by imposing oppressive exactions, or unreasonable tolls upon passengers, vessels, goods, wares, merchandise, or other articles. Neither party, however, shall withdraw the aforesaid protection and guarantee without first giving six months' notice to the other.
