Which country is in the middle of earth?

Jules Vernes classic literature 'journey to the centre of the earth' tell the story of an intrepid German explorer who finds himself dealing with various monsters and other hazards during his decent to the earths core. This was all fiction though, scientists believe that there is a molten core of iron and nickel there so no country. We have yet to explore this area of earth though, so this has not been confirmed.
