/dɪˈklærətɪv ˈθɪəri/ – Phrase
Definition: lý thuyết tuyên bố công nhận (trong luật pháp quốc tế).
A more thorough explanation: The declarative theory is a legal concept that refers to the principle that a state’s recognition of another state’s sovereignty is based on the latter’s ability to declare its independence and govern its territory without interference from external authorities. This theory emphasizes the importance of a state’s ability to effectively exercise control over its territory and population in order to be recognized as a sovereign entity by other states.
Example: The declarative theory of statehood asserts that a state exists when it is recognized as such by other states in the international community.
