Q.What are the various means by which countries are trying to strengthen their own domestic economies?

Protectionist trade policies are measures a government uses to shield its own producers from foreign competition, so that domestic industry, employment and output are strengthened at the expense of freely flowing imports. Even in an era of globalisation, countries reach for these tools whenever cheap imports threaten local jobs or a strategic sector, or when a nation wants to nurture an infant industry until it can stand on its own.

The main instruments fall into two families. Tariff barriers are taxes on imports that raise the price of foreign goods, making home-made goods relatively cheaper and generating revenue. Non-tariff barriers work without a tax: import quotas that cap the physical quantity allowed in; licensing requirements; stringent quality, health or safety standards that foreign goods struggle to meet; and outright bans. Governments may also subsidise domestic producers so they can undersell imports, offer cheap credit or tax breaks, and manage the exchange rate to keep exports competitive. 'Buy local' campaigns and public-procurement preferences push demand toward home industry.

The intent is to protect and build up the domestic economy — safeguarding employment, conserving foreign exchange, and giving new industries breathing space to achieve scale and efficiency. The trade-off is real: protection shelters producers but forces consumers to pay higher prices and can breed inefficiency if firms never face competition, and it may invite retaliation from trading partners. Recognising these means of protection, and weighing their benefits against their costs, is central to understanding how countries try to strengthen their own economies while still participating in world trade.
