Mali
The center of the Earth has no latitude or longitude. Those scales only apply to the surface. -- The Prime Meridian (zero longitude) runs through Algeria, Mali, Burkina Faso, and Togo, in Africa, then goes on to pass about 15 miles east of the center of Accra, Ghana. -- The equator (zero latitude) passes about 385 miles south of Accra, in the sea. So that's the point of zero latitude, zero longitude.
Timbuktu is not a country. It is a city in Mali, a country in West Africa. Timbuktu is known for its rich history as a center of learning and trade in the region.
When you give a set of latitude/longitude coordinates, you narrow the spot down to a single point, so it's not possible for a whole country to be there. That point is in southwestern France, about 30.4 miles east-northeast of the center of Bordeaux.
