Types Of International Agreements
In other cases, such as New Zealand with the Maori and Canada with its First Nations and First Nations, treaties have allowed Aboriginal people to maintain a modicum of autonomy. Such agreements between colonizers and indigenous peoples are an important part of the political discourse of the late 20th and early 21st centuries, the treaties that are being discussed have an international reputation, as indicated by a UN treaty study.   International contract law has been largely codified by the Vienna Convention on Treaty Law, which sets out the rules and procedures governing the establishment, modification and interpretation of contracts, as well as mediation and resolution of alleged disputes and infringements.  Treaties are considered to be one of the oldest manifestations of international relations as the main source of international law.  The separation between the two is often unclear and is often politicized in disagreements within a government over a treaty, as a contract cannot be implemented without the correct modification of national legislation. When a treaty requires laws of application, a state may be late in its obligations if its legislator does not pass the necessary national laws. Before 1871, the U.S. government regularly entered into contracts with Indians, but the Indians Appropriation Act of March 3, 1871 (Chapter 120, 16 Stat. 563) had a horseman (25 US. C No.
71), which effectively ended the drafting of presidential treaties by declaring that no Indian nation or Indian tribe can be recognized as a nation, tribe or independent power with which the United States can enter into contractual contracts. After 1871, the federal government continued to maintain similar contractual relations with Indian tribes through agreements, statutes and executive ordinances.  A treaty is a formal and binding written agreement that has been concluded by actors in international law, usually sovereign states and international organizations, but which may involve individuals and other actors.  A treaty can also be described as an international agreement, protocol, treaty, convention, pact or exchange of letters. Regardless of terminology, only instruments that are binding on the parties are considered treaties of international law.  A treaty is binding under international law. There are several reasons why an otherwise valid and agreed treaty can be rejected as a binding international convention, most of which pose problems related to contract formation.

In addition to treaties, there are other, less formal international agreements.
These include efforts such as the Proliferation Security Initiative (PSI) and the G7 Global Partnership Against the Proliferation of Weapons of Mass Destruction.
