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.

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 1890, the U.S. government banned gentlemen`s agreements in trade and trade relations between nations. A gentlemen`s agreement, or gentleman`s agreement, is an informal and legally 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.
