<P> Following the Spanish--American War, Roosevelt believed that the United States had emerged as a world power, and he sought ways to assert America's newly - eminent position abroad . In 1905, Roosevelt offered to mediate a treaty to end the Russo - Japanese War . The parties agreed to meet in Portsmouth, New Hampshire and they resolved the final conflict over the division of Sakhalin--Russia took the northern half, and Japan the south; Japan also dropped its demand for an indemnity . Roosevelt won the Nobel Peace Prize for his successful efforts in bringing about the Treaty of Portsmouth . George E. Mowry concludes that Roosevelt handled the arbitration well, doing an "excellent job of balancing Russian and Japanese power in the Orient, where the supremacy of either constituted a threat to growing America". Roosevelt also played a major role in mediating the First Moroccan Crisis by calling the Algeciras Conference, which averted war between France and Germany . </P> <P> Roosevelt's presidency saw the strengthening of ties with Great Britain . The Great Rapprochement had begun with British support of the United States during the Spanish--American War, and it continued as Britain withdrew its fleet from the Caribbean in favor of focusing on the rising German naval threat . In 1901, Britain and the United States signed the Hay--Pauncefote Treaty, abrogating the Clayton--Bulwer Treaty, which had prevented the United States from constructing a canal connecting the Pacific and Atlantic Ocean . The long - standing Alaska boundary dispute was settled on terms favorable to the United States, as Great Britain was unwilling to alienate the United States over what it considered to be a secondary issue . As Roosevelt later put it, the resolution of the Alaskan boundary dispute "settled the last serious trouble between the British Empire and ourselves ." </P> <P> The Gentlemen's Agreement of 1907 resolved unpleasant racial tensions with Japan . Tokyo was angered over the segregation of Japanese children in San Francisco schools . The tensions were ended, but Japan also agreed not to allow unskilled workers to emigrate to the U.S. </P> <P> In December 1902, the Germans, British, and Italians sought to impose a naval blockade against Venezuela in order to force the repayment of delinquent loans . Roosevelt was particularly concerned with the motives of Germany's Kaiser Wilhelm . He succeeded in getting the aggressors to agree to arbitration by a tribunal at The Hague, and averted the Venezuela Crisis of 1902--1903 . The latitude granted to the Europeans by the arbiters was in part responsible for the "Roosevelt Corollary" to the Monroe Doctrine, which the President issued in 1904: "Chronic wrongdoing or an impotence which results in a general loosening of the ties of civilized society, may in America, as elsewhere, ultimately require intervention by some civilized nation, and in the Western Hemisphere, the adherence of the United States to the Monroe doctrine may force the United States, however reluctantly, in flagrant cases of such wrongdoing or impotence, to the exercise of an international police power ." </P>
