Free trade is a trade policy that does not restrict imports or exports. It can also be understood as a free-market idea applied in international trade. In view of this, most nations are part of the World Trade Organisation Multilateral Trade Agreements. In Africa, the birth of the African Union (AU) and the African Continental Free Trade Agreement (AfCFTA) affirms the importance
of free trade. Regardless, some governments support protectionism, the opposite of free
trade, thus interfere in free trade agreements.
Requirements:
a) Examine why some governments interfere in free trade agreements. 
b) Discuss at least five (5) non-tariff barriers to trade
