On the west coast, an intense anti-Japanese atmosphere developed. U.S. President Theodore Roosevelt did not want to anger Japan by passing laws banning Japanese immigration to the United States, as had happened with Chinese immigration. Instead, there was an informal “gentlemen`s agreement” (1907-1908) between the United States and Japan, in which Japan ensured that there was little or no movement in the United States. The agreements were concluded by U.S. Secretary of State Elihu Root and Japanese Secretary of State Tadasu Hayashi. The agreement banned the emigration of Japanese workers to the United States and repealed the order of segregation of the San Francisco School Board in California, which had humiliated and angered the Japanese. The agreement did not apply to the territory of Hawaii, which was then treated as separate and separate from the United States. The agreements remained in effect until 1924, when Congress banned all immigration from Japan.  Similar anti-Japanese sentiments in Canada led simultaneously to Hayashi Lemieux`s agreement, also known as the Gentlemen`s Agreement of 1908, with substantially similar clauses and effects.  An ue-Canada agreement was reached in 1996. A report by the U.S.
House of Representatives detailing its United States Steel Corporation investigation stated that in the 1890s there were two general types of associations or bulk consolidations between steel and ferrous interests in which different groups owned ownership, as well as a high degree of independence: the “pool” and the “Gentleman`s Agreement.”  The latter type lacked a formal organisation to regulate production or prices or forfeiture rules in the event of infringement.  The effectiveness of the agreement relied on members to meet informal commitments.  Gentlemen`s agreements have come to regulate international activities such as the coordination of monetary or trade policy.  According to Edmund Osmasczyk in the United Nations Encyclopedia and International Agreements, it is also defined as “an international term for an oral and unwritten but fully valid agreement.”  This type of agreement may allow a nation to circumvent national legal requirements to enter into a formal contract or it may be useful for a government to want to enter into a secret agreement that does not engage the next government.  According to another author, all international agreements are gentlemen`s agreements because, just before the war, they are all unenforceable.  Osmaczyk noted that there was a difference between gentlemen`s open agreements and secret diplomatic agreements.  In the United States, in 1890, the prohibition of gentlemen`s agreements was introduced in interstate trade relations because the secrecy of these agreements was beyond anyone`s control.  Gentlemen`s agreements were a widespread discriminatory tactic, which would have been more common than restrictive alliances to preserve the homogeneity of upper-class neighborhoods and suburbs in the United States.  The nature of these agreements made it extremely difficult to prove or follow them, and they were long after the U.S. Supreme Court decisions in Shelley/.
Kraemer and Barrows v. Jackson.  A source indicates that the gentlemen`s agreements are “probably still in place” but that their use has declined sharply.  Until Jackie Robinson was hired by the Brooklyn Dodgers in 1946, a gentlemen`s agreement ensured that African-American players were excluded from organized baseball.  This includes validating by all necessary means the formal declaration (declaration of honour) signed by the applicants in the application form.
