Answer:
Monopoly
Step-by-step explanation:
Ali's country saw the it can produce much more coffee beans than the other countries, but also having much higher quality to offer too. The economy started to focus more on this agricultural branch, so Ali's country became the dominant producer of coffee beans, holding pretty much all the market in the trade bloc in which the country is a member. The country effectively managed to create a monopoly when it comes to the production, trade, and sell of coffee. By using its excellent conditions for production of it, it managed to totally dominated the market, thus having no real competition, and being able to control the prices as its suits it.
