Move around the world by naming every country's nearest neighbour (as measured from geographical centre to geographical centre) that hasn't already been named. Start with the country that is the most distant from any other country.
If you think it sounds too easy with a map to help, you can do it without.

The geographical centres of Pacific nations are not necessarily at all close to the centre of their shaded region!
Apparently the geographical center doesn't have anything to to with the middle of the country. There's no way the g.c. of any country close to the USA are a couple hundred miles apart.. The center of the USA is hundreds of miles from the nearest border.
Is French Guiana taken into account for France's location in the same way? I was expecting France to be a tricky answer in a strange place but it didn't seem to be.
I mostly got the centroids of countries using Geopandas but very small countries don't show up in its lowres world coordinates dataset. Tuvalu is one of them. I got the coordinates of the missing nations from https://developers.google.com/public-data/docs/canonical/countries_csv, which places Tuvalu at 177.6E, 7.1S. There's no information on how those points were calculated but it seems reasonable given the locations of the extreme points of the country.
Great quiz, and a challenge to do. Maybe would help to have the option to have missing countries highlighted? If you've moved to a less obvious neighbour then its easy to forget the small countries you left behind. And fun to see just how apart New Zealand and Australia really are : )
