The principal treaty, of which the ratifications were exchanged August 16, 1859, recites that "the United States of America and the Ta Tsing Empire, desiring to maintain firm, lasting, and sincere friendship, have resolved to renew, in a manner clear and positive, by means of a treaty or general convention of peace, amity, and commerce, the rules which shall in future be mutually observed in the intercourse of their respective countries," and proceeds in its thirty articles to lay out a careful and comprehensive system for the commercial relations of our people with China. The main substance of all the provisions of this treaty is to define and secure the rights of our people in respect of access to, residence and protection in, and trade with China. The actual provisions in our favor in these respects were framed to be, and have been found to be, adequate and appropriate to the interests of our commerce, and by the concluding article we receive the important guaranty that—
Should at any time the Ta Tsing Empire grant to any nation, or the merchants or citizens of any nation, any right, privilege, or favor, connected either with navigation, commerce, political or other intercourse, which is not conferred by this treaty, such right, privilege, and favor shall at once freely inure to the benefit of the United States, its public officers, merchants, and citizens.
Against this body of stipulations in our favor and this permanent engagement of equality in respect of all future concessions to foreign nations the general promise of permanent peace and good offices on our part seems to be the only equivalent. For this the first article undertakes as follows:
There shall be, as there have always been, peace and friendship between the United States of America and the Ta Tsing Empire, and between their people respectively. They shall not insult or oppress each other for any trifling cause, so as to produce an estrangement between them; and if any other nation should act unjustly or oppressively, the United States will exert their good offices, on being informed of the case, to bring about an amicable arrangement of the question, thus showing their friendly feelings.
At the date of the negotiation of this treaty our Pacific possessions had attracted a considerable Chinese emigration, and the advantages and the inconveniences felt or feared therefrom had become more or less manifest; but they dictated no stipulations on the subject to be incorporated in the treaty. The year 1868 was marked by the striking event of a spontaneous embassy from the Chinese Empire, headed by an American citizen, Anson Burlingame, who had relinquished his diplomatic representation of his own country in China to assume that of the Chinese Empire to the United States and the European nations. By this time the facts of the Chinese immigration and its nature and influences, present and prospective, had become more noticeable and were more observed by the population immediately affected and by this Government. The principal feature of the Burlingame treaty was its attention to and its treatment of the Chinese immigration and the Chinese as forming, or as they should form, a part of our population. Up to this time our uncovenanted hospitality to immigration, our fearless liberality of citizenship, our equal and comprehensive justice to all inhabitants, whether they abjured their foreign nationality or not, our civil freedom, and our religious toleration had made all comers welcome, and under these protections the Chinese in considerable numbers had made their lodgment upon our soil.
The Burlingame treaty undertakes to deal with this situation, and its fifth and sixth articles embrace its most important provisions in this regard and the main stipulations in which the Chinese Government has secured an obligatory protection of its subjects within our territory. They read as follows:
ART. V. The United States of America and the Emperor of China cordially recognize the inherent and inalienable right of man to change his home and allegiance, and also the mutual advantage of the free migration and emigration of their citizens and subjects respectively from the one country to the other for purposes of curiosity, of trade, or as permanent residents. The high contracting parties therefore join in reprobating any other than an entirely voluntary emigration for these purposes. They consequently agree to pass laws making it a penal offense for a citizen of the United States or Chinese subjects to take Chinese subjects either to the United States or to any other foreign country, or for a Chinese subject or citizen of the United States to take citizens of the United States to China or to any other foreign country, without their free and voluntary consent, respectively.
ART. VI. Citizens of the United States visiting or residing in China shall enjoy the same privileges, immunities, or exemptions in respect to travel or residence as may there be enjoyed by the citizens or subjects of the most favored nation, and, reciprocally, Chinese subjects visiting or residing in the United States shall enjoy the same privileges, immunities, and exemptions in respect to travel or residence as may there be enjoyed by the citizens or subjects of the most favored nation. But nothing herein contained shall be held to confer naturalization upon citizens of the United States in China, nor upon the subjects of China in the United States.
An examination of these two articles in the light of the experience then influential in suggesting their "necessity" will show that the fifth article was framed in hostility to what seemed the principal mischief to be guarded against, to wit, the introduction of Chinese laborers by methods which should have the character of a forced and servile importation, and not of a voluntary emigration of freemen seeking our shores upon motives and in a manner consonant with the system of our institutions and approved by the experience of the nation. Unquestionably the adhesion of the Government of China to these liberal principles of freedom in emigration, with which we were so familiar and with which we were so well satisfied, was a great advance toward opening that Empire to our civilization and religion, and gave promise in the future of greater and greater practical results in the diffusion throughout that great population of our arts and industries, our manufactures, our material improvements, and the sentiments of government and religion which seem to us so important to the welfare of mankind. The first clause of this article secures this acceptance by China of the American doctrines of free migration to and fro among the peoples and races of the earth.
The second clause, however, in its reprobation of "any other than an entirely voluntary emigration" by both the high contracting parties, and in the reciprocal obligations whereby we secured the solemn and unqualified engagement on the part of the Government of China "to pass laws making it a penal offense for a citizen of the United States or Chinese subjects to take Chinese subjects either to the United States or to any other foreign country without their free and voluntary consent," constitutes the great force and value of this article. Its importance both in principle and in its practical service toward our protection against servile importation in the guise of immigration can not be overestimated. It commits the Chinese Government to active and efficient measures to suppress this iniquitous system, where those measures are most necessary and can be most effectual. It gives to this Government the footing of a treaty right to such measures and the means and opportunity of insisting upon their adoption and of complaint and resentment at their neglect. The fifth article, therefore, if it fall short of what the pressure of the later experience of our Pacific States may urge upon the attention of this Government as essential to the public welfare, seems to be in the right direction and to contain important advantages which once relinquished can not be easily recovered.
