Final answer:
The prohibition of sugar and cigar imports from Cuba by the United States is an example of an economic embargo, a trade barrier implemented due to US concerns with Cuba's nationalization policies and movement towards communism.
Step-by-step explanation:
The United States has prohibited the import of sugar and cigars from Cuba. This is an example of an economic embargo. An economic embargo is a form of trade barrier where one country ceases trade with another. In the context of US-Cuba relations, the embargo was established due to the nationalization of businesses and properties by Fidel Castro's government, which impacted US business interests and was seen as leading Cuba towards communism. This economic sanction started in 1960 and subsequently intensified, affecting goods such as sugar which was a significant import from Cuba to the United States.
Besides the embargo, trade barriers can include tariffs and quotas, like the theoretical sugar import quota of seven tons that would limit the amount of sugar that could be imported into the United States from a specific country, thereby influencing domestic prices and supply.
