Uff, this was difficult! Great job, though, it must have taken you ages to come up with it! But I had the same problem as superpik - I felt like North Macedonia would fit the clues as well. Also clue 6 was a bit confusing, I wasn't sure if it's meant just for the non-island countries or also the other way around - as in does a multi-word island country have to border another multi-word country?
Kosovo with Kiribati
Nauru with Malta
Marshall islands with North Macedonia
Spain with Samoa

Any multi-word country (island countries included) must border a multi-word island country, that's the idea. Thanks for your comment!
