EMEA is used most often in situations involving international trade and business. It is less of a political term and more of a geographical term. For example, a nation outside of the EMEA, like the United States, might talk about Russia as part of the EMEA. Bolivia might say the EMEA when they mean Europe, the Middle East, Africa, and India. The point here is that the EMEA is not a complete set-in-stone term. While it most commonly refers to Europe, the Middle East, and Africa, it is not uncommon for other nations to tweak the countries they include under the umbrella term.
