Why some countries do not benefit from international trade?

Some countries do not benefit from international trade due to factors such as lack of infrastructure, political instability, and limited access to education and technology, which hinder their ability to compete globally. Additionally, they may rely heavily on a narrow range of exports, making them vulnerable to market fluctuations. Trade barriers, such as tariffs and quotas imposed by other nations, can also limit their access to larger markets. Lastly, unequal bargaining power can lead to exploitative trade agreements that do not favor the less developed nations.
