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.  In many cases, the end result may be a 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.» In the automotive industry, Japanese manufacturers have agreed that no standard vehicle would have more than 276 hp (206 kW; 280 CH); 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. 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.
 A gentlemen`s agreement or gentleman`s agreement is an informal and non-binding agreement between two or more parties. It is usually oral, but it can be written or simply understood as part of a tacit agreement by convention or by mutually beneficial label. The essence of a gentlemen`s agreement is that it depends on the honour of the parties for its achievement, rather than being enforceable in one way or another. It differs from a legal agreement or a contract. A gentlemen`s agreement is an informal agreement or transaction, often unwritten, 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. A gentleman`s agreement, defined at the beginning of the 20th century as «an agreement between gentlemen who looks at price control,» has been described by one source as the most lax form of a «pool.»  Such agreements have been declared in all industrial sectors and are numerous in the steel and steel industry.  In 1890, the U.S. government banned gentlemen`s agreements in trade and trade relations between nations.https://wikifama.com/gentlemens-agreement-us/
