A more thorough explanation:

Definition: Jus gentium publicum refers to the legal system that governs the relationships between nations. It is also known as international law and includes not only nations but also international organizations and individuals who invoke their human rights or commit war crimes. It is a set of rules that countries agree to follow when dealing with each other.

Examples: One example of jus gentium publicum is the Geneva Conventions, which are a set of international laws that protect people who are not taking part in a conflict, such as civilians, medical personnel, and prisoners of war. Another example is the United Nations Convention on the Law of the Sea, which sets out the rights and responsibilities of countries in their use of the world's oceans.

Explanation: These examples illustrate how jus gentium publicum is used to regulate the behavior of nations and individuals in their interactions with each other. The Geneva Conventions provide a framework for how countries should treat people who are not taking part in a conflict, while the United Nations Convention on the Law of the Sea sets out rules for how countries should use the world's oceans. These agreements help to promote peace and cooperation between nations by providing a common set of rules that everyone agrees to follow.
