Country Logic Puzzle by Scambigol #46

Follow instructions carefully!

1) No country appears more than once
2) To properly complete the quiz you must never write down a country if you're not 100% sure it's the one that goes there!

A: Island countries have become transparent, all other countries are answers
B: Each column contains countries with the same colour as the cell on top (eg column A contains countries that are red on the map)
C: Countries in rows 4 and 9 have a thicker cell border in the world map and in the answers grid
C: Below each cell arrows indicate borders with nearby cells, namely:
 → borders country to the right
 ↙ borders country one down one left
 ↘ borders country one down one right
 ↓ borders country below
 ⇓ borders country two below
 ⤋ borders country three below
D: Red arrows refer to 4 "shortest swim across" borders, crossing Bab-El-Mandeb, Øresund, Gulf of Finland, Bering Strait
If the ↓ is present in the column header it means it is present throughout the colum (this means the countries make a 'chain')
