What is the main difference between a bilateral and a multilateral treaty?

The main difference between a bilateral and a multilateral treaty lies in the number of parties involved. Bilateral treaties are agreements formed between two sovereign states, while multilateral treaties are agreements between three or more states. This distinction is fundamental because it impacts the complexity of negotiations, the scope of agreements, and the manner in which the treaties are implemented and enforced.

Bilateral treaties typically allow for a more straightforward negotiation process, as only two parties need to agree on the terms. In contrast, multilateral treaties can involve a larger number of negotiating parties, which can complicate the process as it requires consensus or agreement among multiple countries.

Furthermore, assertions about the need for unanimous support in multilateral treaties or claims regarding international recognition do not accurately reflect the nature of treaties in international law. Multilateral treaties can sometimes be adopted with a majority agreement rather than unanimous consent, depending on the treaty’s provisions. Additionally, both bilateral and multilateral treaties can receive international recognition provided they adhere to the relevant legal frameworks.
