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 The agreement banned the emigration of Japanese workers to the United States and repealed the order of segregation of the San Francisco School Board in California, which had humiliated and angered the Japanese.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.  In the automotive industry, Japanese manufacturers have agreed that no standard vehicle would have more than 276 hp (206 kW; 280 hp); The agreement ended in 2005.  German manufacturers limit the maximum speed of high-performance sedans (berlines) and breaks to 250 km/h.   When the Suzuki Hayabusa motorcycle exceeded 310 km/h in 1999, fears of a European ban or regulatory intervention led Japanese and European manufacturers to limit to 300 km/h at the end of 1999 See list of the fastest series bikes.
The end result may, in many cases, be higher cost or lower quality products for consumers. Worse, a gentlemen`s agreement can be used as a means of promoting discriminatory practices, as in a « network of old boys. » Gentlemen`s agreements have often been concluded in international trade and international relations, as well as in most industries. Gentlemen`s agreements were particularly prevalent at the birth of the industrial era and well beyond the first half of the 200th year, as regulations often delayed new business practices. It was found that such agreements were used, among other things, to control prices and limit competition in the steel, iron, water and tobacco industries. 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.  A gentlemen`s agreement is an informal, often unwritten agreement or transaction, which is supported only by the integrity of the other party to effectively comply with its terms. Such an agreement is generally informal, oral and not legally binding. Gentlemen`s agreements have come to regulate international activities as the coordination of monetary or trade policies.  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.
 Similarly, in 1907, Morgan again collaborated with Roosevelt to create a gentlemen`s agreement that would allow the United States.
