Free trade aims to maximise global output through national specialisation
However, there are numerous reasons why countries would seek to limit free trade in order to protect themselves from certain outcomes
The restriction of trade is called protectionism and may take the form of:
- Import tariffs
- Export subsidies
- The use of quotas
- Trade embargoes
Trading partners may retaliate to any methods of protectionism and they should be carefully considered before any implementation

Reason	Explanation
Protect infant (sunrise) industries	New industries may need protection from foreign competition until they become efficient and competitive. Example: A developing country supporting its growing solar panel sector
Protect declining (sunset) industries	Old industries that are shrinking may be protected to slow down job losses and help manage transition. Example: Coal mining in some countries
Protect strategic industries	Essential sectors (like food, energy and defence) are protected to maintain national security Example: Limiting foreign control of telecoms or arms production
Avoid dumping	Dumping is when foreign producers sell goods below cost to gain market share Restrictions help protect domestic firms from unfair competition
Reduce current account deficits	Reducing imports can help improve the balance of payments by reducing the money flowing out of the country
Raise tax revenue	Tariffs on imports generate revenue for governments, which is especially useful in countries with weak tax systems
Restrict demerit goods	Importing goods like alcohol or tobacco may be restricted to reduce harm to public health
Promote environmental sustainability	Restrictions can be placed on goods that damage the environment or are produced in harmful ways Example: Limiting imports from deforestation-linked supply chains

Countries affected by the restrictions may lose export markets
Tensions may increase, possibly leading to trade wars
Can reduce income for producers and lead to job losses abroad
Might encourage affected countries to form alternative trade agreements, leading to a loss of future exports

Advantages	Disadvantages
Protects local jobs and industries Encourages domestic production Increases government revenue through tariffs Can improve trade balance (fewer imports)	Consumers face higher prices and less variety as trade restrictions increase import costs Domestic firms may become less efficient without competition Can provoke retaliation from other countries Slower innovation and limited access to better technology
