Definition: việc giữ nguyên hiệu lực (của hiệp ước quốc tế).
A more thorough explanation: Voluntary validity of a treaty refers to the legal concept that a treaty is considered valid and binding on the parties involved because they have voluntarily agreed to be bound by its terms. This means that the parties have entered into the treaty of their own free will and are not under any external pressure or coercion to comply with its provisions.
Example: The voluntary validity of the treaty was evident as both parties willingly agreed to abide by its terms without any external pressure or coercion.
