In 1852 an expedition was sent to Japan, under the command of Commodore Perry, for the purpose of opening commercial intercourse with that Empire. Intelligence has been received of his arrival there and of his having made known to the Emperor of Japan the object of his visit. But it is not yet ascertained how far the Emperor will be disposed to abandon his restrictive policy and open that populous country to a commercial intercourse with the United States. It has been my earnest desire to maintain friendly intercourse with the Governments upon this continent and to aid them in preserving good understanding among themselves. With Mexico a dispute has arisen as to the true boundary line between our Territory of New Mexico and the Mexican State of Chihuahua. A former commissioner of the United States, employed in running that line pursuant to the treaty of Guadalupe Hidalgo, made a serious mistake in determining the initial point on the Rio Grande; but inasmuch as his decision was clearly a departure from the directions for tracing the boundary contained in that treaty, and was not concurred in by the surveyor appointed on the part of the United States, whose concurrence was necessary to give validity to that decision, this Government is not concluded thereby; but that of Mexico takes a different view of the subject. There are also other questions of considerable magnitude pending between the two Republics. Our minister in Mexico has ample instructions to adjust them. Negotiations have been opened, but sufficient progress has not been made therein to enable me to speak of the probable result. Impressed with the importance of maintaining amicable relations with that Republic and of yielding with liberality to all her just claims, it is reasonable to expect that an arrangement mutually satisfactory to both countries may be concluded and a lasting friendship between them confirmed and perpetuated. Congress having provided for a full mission to the States of Central America, a minister was sent thither in July last. As yet he has had time to visit only one of these States (Nicaragua), where he was received in the most friendly manner. It is hoped that his presence and good offices will have a benign effect in composing the dissensions which prevail among them, and in establishing still more intimate and friendly relations between them respectively and between each of them and the United States.
