Most GMO foods produced are for importation to other countries. Countries who import food they can grow in their country tend to practice GMO and another reason is to enhance the food they  produce in the lab so they sell more in the trade market than other countries making the same supplies.

In Nigeria we produce, more than 60% of the food we eat. Only few are imported even when we can also produce them here too. Meaning, I believe our government will not agree to GMO in Nigeria.
