How do trade barriers affect the african economy today

Trade barriers affect the African economy today as the economy is dependent on the exports largely for the fund.

Explanation:

A trade barrier is where the government imposes a restraint on the export or flow of international goods or services. The common type of trade barrier is a tariff which is a tax imposed on imports. This allows the price of imported goods to rise compared to domestic goods. Excessive tariffs affect international trade. For countries like Africa which are dependent on exports to fund their economy, trade barriers can cause their economy to suffer. This causes an increase in supply and businesses are forced to sell their goods at a very low price which affects the economy gravely.
