For more details, read this blog „Treaty and Convention: How to Distinguish These Two” International Agreements are formal agreements or commitments between two or more countries. An agreement between two countries is described as „bilateral,” while an agreement between several countries is „multilateral.” Countries bound by countries bound by an international convention are generally referred to as „Parties.” The contract applies in particular to a formal written agreement, often of a commercial nature, which is therefore expressly formulated as having the force of law. Under international law, a treaty is a legally binding agreement between states (countries). A treaty can be called a convention, protocol, pact, agreement, etc. It is the content of the agreement, not its name, that makes it a treaty. Thus, the Geneva Protocol and the Biological Weapons Convention are the two treaties, although neither treaty in its name. Under U.S. law, a treaty is a legally binding agreement between countries that requires ratification and „consultation and approval” of the Senate. All other agreements (internationally treated) are called executive agreements, but are nevertheless legally binding on the United States under international law.
Treaties can be designated by a number of names: international conventions, international agreements, alliances, final acts, charters, declarations of intent, protocols, pacts, agreements and constitutions for international organizations. Normally, these different names have no legal value in international law (see the following section for the difference in U.S. law). Contracts can be bilateral (two parties) or multilateral (between several parties) and a contract generally involves only the contracting parties. An agreement enters into force if the entry-into-force conditions set out in the agreement are met. Bilateral agreements generally come into force when both parties agree to be linked from a given date. An agreement is the regulatory framework for the parties that approve the agreement in order to solve a problem that affects a larger part of the world. An agreement (see also THE MONOPOLY) is a written agreement or between opposing nations, usually for the regulation of sexual relations between them in view or during the war.
The pact, as used by an agreement between individuals or groups, is generally interchangeable with compact. In addition to treaties, there are other less formal international agreements.
