Describe ways that nations restrict foreign trade.?

Answer 1

Embargoes, tariffs, quotas, support of local industries by subsidies, etc

Answer 2

There are three basic ways. The first is tariffs which is a tax on imports. The higher the tariff, the more expensive the import and the less people will want to buy.

The second is quotas. This is a limitation on the quantity of a product that can be imported.

The third is health and safety regulations that prohibit the importation of products determined to be unhealthy or unsafe. Though these are supposed to protect consumers, they are often used as an excuse to keep out foreign made products by falsely claiming that they are unhealthy or unsafe.

Answer 3

they don't restrict foreign trade per se, but they restrict trade on a particular product.

Outright some products are not allowed to be imported because a certain country is producing it, and if importation is allowed it will compete with its manufacturers.
