When a country decides not to trade at all with another country, it is called an embargo. An embargo is a government order that restricts commerce or exchange with a specified country. This is usually done for political, economic, or social reasons. Unlike quotas or tariffs, which limit the quantity or increase the cost of goods traded, an embargo completely stops trade. Specialization, on the other hand, refers to a country focusing on producing specific goods or services efficiently, which is unrelated to trade restrictions.
