"Soon after, nation Y increased tariffs on imports of precious metals from country X" indicates retaliatory protectionism.
<u>Explanation:</u>
A policy that prevent and give coverage to domestic industries from external unfair competition is called as "Trade protectionism". Protectionism is a defensive measure which has a political motivation. It does work in the short run.
The four central instruments are quotas, tariffs, subsidies and manipulation of the currency in order to boost the domestic production of goods and services. Protectionism deducts the consumers and workers of low-wage commodities in the developed countries.
