# Treaty of Amity and Commerce between Siam and the United States, 1833

His Majesty the Sovereign and Magnificent King in the City of Sia-Yut'hia, has appointed the Chau Phaya-Phraklang, one of the first Ministers of State, to treat with Edmund Roberts, Minister of the United States of America, who has been sent by the Government thereof, on its behalf, to form a treaty of sincere friendship and entire good faith between the two nations. For this purpose the Siamese and the citizens of the United States of America shall, with sincerity, hold commercial intercourse in the Ports of their respective nations as long as heaven and earth shall endure.
This Treaty is concluded on Wednesday, the last of the fourth month of the year 1194, called Pi-marong-chat-tavasok, or the year of the Dragon, corresponding to the 20th day of March, in the year of our Lord 1833. One original is written in Siamese, the other in English; but as the Siamese are ignorant of English, and the Americans of Siamese, a Portuguese and a Chinese translation are annexed, to serve as testimony to the contents of the Treaty. The writing is of the same tenor and date in all the languages aforesaid. It is signed on the one part, with the name of the Chau Phaya-Phraklang, and sealed with the seal of the lotus flower, of glass. On the other part, it is signed with the name of Edmund Roberts, and sealed with a seal containing an eagle and stars.
One copy will be kept in Siam, and another will be taken by Edmund Roberts to the United States. If the Government of the United States shall ratify the said Treaty, and attach the Seal of the Government, then Siam will also ratify it on its part, and attach the Seal of its Government.
Article I
There shall be a perpetual Peace between the Magnificent King of Siam and the United States of America.
Article II
The Citizens of the United States shall have free liberty to enter all the Ports of the Kingdom of Siam, with their cargoes, of whatever kind the said cargoes may consist; and they shall have liberty to sell the same to any of the subjects of the King, or others who may wish to purchase the same, or to barter the same for any produce or manufacture of the Kingdom, or other articles that may be found there. No prices shall be fixed by the officers of the King on the articles to be sold by the merchants of the United States, or the merchandise they may wish to buy, but the Trade shall be free on both sides to sell, or buy, or exchange, on the terms and for the prices the owners may think fit. Whenever the said citizens of the United States shall be ready to depart, they shall be at liberty so to do, and the proper officers shall furnish them with Passports: Provided always, there be no legal impediment to the contrary. Nothing contained in this Article shall be understood as granting permission to import and sell munitions of war to any person excepting to the King, who, if he does not require, will not be bound to purchase them; neither is permission granted to import opium, which is contraband; or to export rice, which cannot be embarked as an article of commerce. These only are prohibited.
Article III
Vessels of the United States entering any Port within His Majesty's dominions, and selling or purchasing cargoes of merchandise, shall pay in lieu of import and export duties, tonnage, licence to trade, or any other charge whatever, a measurement duty only, as follows: The measurement shall be made from side to side, in the middle of the vessel's length; and, if a single-decked vessel, on such single deck; if otherwise, on the lower deck. On every vessel selling merchandise, the sum of 1700 Ticals, or Bats, shall be paid for every Siamese fathom in breadth, so measured, the said fathom being computed to contain 78 English or American inches, corresponding to 96 Siamese inches; but if the said vessel should come without merchandise, and purchase a cargo with specie only, she shall then pay the sum of 1,500 ticals, or bats, for each and every fathom before described. Furthermore, neither the aforesaid measurement duty, nor any other charge whatever, shall be paid by any vessel of the United States that enters a Siamese port for the purpose of refitting, or for refreshments, or to inquire the state of the market.
Article IV
If hereafter the Duties payable by foreign vessels be diminished in favour of any other nation, the same diminution shall be made in favour of the vessels of the United States.
Article V
If any vessel of the United States shall suffer shipwreck on any part of the Magnificent King's dominions, the persons escaping from the wreck shall be taken care of and hospitably entertained at the expense of the King, until they shall find an opportunity to be returned to their country; and the property saved from such wreck shall be carefully preserved and restored to its owners; and the United States will repay all expenses incurred by His Majesty on account of such wreck.
Article VI
If any citizen of the United States, coming to Siam for the purpose of trade, shall contract debts to any individual of Siam, or if any individual of Siam shall contract debts to any citizen of the United States, the debtor shall be obliged to bring forward and sell all his goods to pay his debts therewith. When the product of such bona fide sale shall not suffice, he shall no longer be liable for the remainder, nor shall the creditor be able to retain him as a slave, imprison, flog, or otherwise punish him, to compel the payment of any balance remaining due, but shall leave him at perfect liberty.
Article VII
Merchants of the United States coming to trade in the Kingdom of Siam and wishing to rent houses therein, shall rent the King's Factories, and pay the customary rent of the country. If the said merchants bring their goods on shore, the King's officers shall take account thereof, but shall not levy any duty thereupon.
Article VIII
If any citizens of the United States, or their vessels, or other property, shall be taken by pirates and brought within the dominions of the Magnificent King, the persons shall be set at liberty, and the property restored to its owners.
Article IX
Merchants of the United States, trading in the Kingdom of Siam, shall respect and follow the laws and customs of the country in all points.
Article X
If thereafter any foreign nation other than the Portuguese shall request and obtain His Majesty's consent to the appointment of Consuls to reside in Siam, the United States shall be at liberty to appoint Consuls to reside in Siam, equally with such other foreign nation.
Whereas, the undersigned, Edmund Roberts, a citizen of Portsmouth, in the State of New Hampshire, in the United States of America, being duly appointed as Envoy, by Letters Patent, under the Signature of the President and Seal of the United States of America, bearing date at the City of Washington, the 26th day of January, in the year of our Lord 1832, for negotiating and concluding a Treaty of Amity and Commerce between the United States of America and His Majesty, the King of Siam.
