What is the definition of protectionism?

Protectionism is an economic policy aimed at shielding a country's domestic industries from foreign competition by imposing tariffs, quotas, and other trade barriers. This approach seeks to promote local businesses and preserve jobs, but it can also lead to higher prices for consumers and strained international relations. By limiting imports, protectionism aims to encourage domestic production and reduce reliance on foreign goods. However, it often sparks debates about its long-term impacts on economic growth and global trade dynamics.
