A government-imposed restriction on trade or other commercial activity with a particular country or group of countries.
Here's why this is the best definition:
* Comprehensive: It encompasses all forms of restrictions, including trade in goods, services, and financial transactions.
* Specific: It clarifies that the restriction is imposed by a government, not an individual or private entity.
* Targeted: It highlights that embargoes are aimed at specific countries or groups of countries, not a general ban on trade.
While other definitions may focus on specific aspects, such as the purpose of an embargo or the methods used to enforce it, this definition captures the core essence of an embargo in a clear and concise manner.
