After the Vancouver riots, Prime Minister Wilfrid Laurier sent Lemieux to Japan to talk about restrictions on Japanese immigration. Canada could not explicitly prohibit immigration to the Japanese, as an existing trade agreement with Japan guaranteed the Japanese full freedom to enter, travel or stay in any part of the Dominion.  Lemieux asked Hayashi to voluntarily limit immigration in the interest of Anglo-Japanese harmony. While Japan initially was reluctant to impose restrictions on its citizens, they concluded that it was necessary to work with Canada to maintain good relations with the British Empire.  Although the agreement limited the number of adult men who could enter Canada, it did not provide for restrictions on the wives of Japanese immigrants. After the introduction of the quota, a large number of Japanese women began to migrate to Canada as «image brides.» Japanese men in Canada would choose brides based on photos sent by relatives to Japan. After registering her marriage in Japan, the bride was granted a passport to Canada. The arrival of more Japanese women facilitated a natural increase in Canada`s Japanese population.  Many Japanese Americans argued that the separation of schools was contrary to the 1894 treaty, which did not explicitly address education, but indicated that the Japanese would obtain equal rights in America. According to the U.S. Supreme Court review decisions (Plessy v. Ferguson, 1896), a state did not violate the equality clause of the U.S.
Constitution by imposing racial segregation as long as the various institutions are essentially equal. Tokyo newspapers have denounced segregation as an insult to Japanese pride and honour. The Japanese government wanted to protect its reputation as a world power. Government officials became aware of the crisis and intervention was needed to maintain diplomatic peace.  President Roosevelt had three objectives to resolve the situation: to show Japan that California`s policy did not reflect the ideals of the entire country to force San Francisco to eliminate the policy of segregation and to find a solution to the problem of Japanese immigration. Victor Metcalf, Minister of Trade and Labour, was sent to investigate the problem and force the repeal of the policy. He did not succeed because local officials wanted Japanese exclusion. Roosevelt tried to put pressure on the school`s management, but it won`t give way. On February 15, 1907, the parties reached a compromise. If Roosevelt could ensure the suspension of Japanese immigration, the school board would allow Japanese-American students to attend public schools.
