What is an embargo in terms of international trade?

An embargo in terms of international trade refers to a restriction or prohibition on specific imports or exports between countries. When a country imposes an embargo, it effectively halts trade of particular goods, which can include food products, in response to political, economic, or security reasons. This is often used as a tool for diplomacy or to apply pressure on nations regarding specific behaviors or policies.

In this context, the correct answer accurately captures the essence of an embargo as it specifically mentions the limitation of food imports, encapsulating the broader concept of restricting trade in certain goods. The other options do not reflect the definition of an embargo; for example, tariffs or taxes relate to the monetary cost imposed on traded goods, subsidies are financial incentives provided to support producers domestically, and licensing requirements pertain to the permissions necessary for engaging in trade, none of which define an embargo accurately.
