In economic terms, what is a trade barrier?

 A trade barrier is a restriction on international trade.

Explanation: Trade barriers are government efforts to control/block any trades outside the country. They decrease general economic efficiency, which can be further supported by the theory of comparative advantage. Comparative advantage means that when a country produces a good for a lower opportunity cost than other areas. A country with comparative advantage makes trade-offs worth it.

Hope this helps! Let me know if you have any other questions. :)

can you explain a little further maybe give multiple choice? ?
