US Presidency
1857

The Shah has manifested an earnest disposition to cultivate friendly relations with our country, and has expressed a strong wish that we should be represented at Teheran by a minister plenipotentiary; and I recommend that an appropriation be made for this purpose. Recent occurrences in China have been unfavorable to a revision of the treaty with that Empire of the 3d July, 1844, with a view to the security and extension of our commerce. The twenty-fourth article of this treaty stipulated for a revision of it in case experience should prove this to be requisite, in which case the two Governments will, at the expiration of twelve years from the date of said convention, treat amicably concerning the same by means of suitable persons appointed to conduct such negotiations. These twelve years expired on the 3d July, 1856, but long before that period it was ascertained that important changes in the treaty were necessary, and several fruitless attempts were made by the commissioner of the United States to effect these changes.
