If the United States were to impose an embargo against Saudi Arabia’s oil, targeting only ONE ITEM, this would be an example of what?

It would be an example of an economic sanction.

Explanation:

Economic sanctions are the measures taken by a nation to punish economically and financially another for its breaches, be they commercial or legal, committed against the sanctioning nation itself, or against others, or against citizens of these nations.

Thus, through the imposition of tariffs, embargoes, freezing of accounts, etc., nations seek to cause economic damage that is the reason for the cessation of the actions that motivate the sanction. For example, the imposition of tariffs by the US on China during the 2019/20 Trade War was intended to stop the dumping carried out by the Chinese government.
