If the removal of trade barriers is so beneficial to international economic growth, why would a nation continue to restrict trade on some imported or exported products?

Start by understanding what trade barriers are. Trade barriers are measures that governments or public authorities impose to restrict international trade. These can include tariffs, import quotas, export quotas, and other non-tariff barriers, such as regulations and subsidies.

The removal of trade barriers can lead to increased international trade, greater economic efficiency and higher living standards. This is because it allows for the specialization of countries in the production of goods and services they have comparative advantages in, leading to greater efficiency and lower costs of production. Consequently, consumers can have access to a greater variety of goods at lower prices, promoting economic growth.

Despite the benefits of removing trade barriers, nations may still choose to restrict trade on some imported or exported products for various reasons. These may include: 1. Protecting domestic industries: If a nation's domestic industry is unable to compete with foreign imports, the government may impose import restrictions to protect it from competition, supporting jobs and businesses. 2. National security: A nation may restrict trade on certain products to ensure self-sufficiency in essential goods and services, such as defense equipment, food, and energy, in the event of trade disruptions or conflicts. 3. Protecting public health and the environment: Some trade restrictions may be put in place to protect public health and the environment. For example, a country might impose tariffs on goods that are produced using harmful chemicals or processes. 4. Safeguarding cultural identity: Some nations may restrict the import of goods and services that may dilute or replace local customs and traditions, in order to preserve their cultural identity. 5. Correcting trade imbalances: A nation may choose to impose trade restrictions on certain products in order to correct a significant trade deficit with one or more trading partners. 6. Generating government revenue: Tariffs can be an important source of revenue for some countries, especially those with limited tax collection capabilities or high levels of public debt.

While the removal of trade barriers can be beneficial for international economic growth and lead to improved living standards, there are situations where a nation might choose to restrict trade on certain products. These may include protecting domestic industries, ensuring national security, safeguarding public health and the environment, preserving cultural identity, correcting trade imbalances, and generating government revenue. As such, it is important for policymakers to carefully weigh the potential benefits and drawbacks of trade liberalization in determining the appropriate level of trade restrictions for their country.
