Answer: Protectionism
Step-by-step explanation:
Protectionism occurs when the industries in a particular country are being protected from foreign competition by the government of that economy. Protectionism is done through the imposition of tariffs, quotas or total ban on the products of other countries.
In the question, the tariff on rice is an example of protectionism as the tariff will lead to an increase in the price of the foreign rice and the people will have to buy from the local rice suppliers. In this case, the local industry is protected.
