Yes it's mostly down to connections between countries, both cultural and historical. Cyprus and Greece being the best example, nothing political its just the countries are very closely affiliated, half of Cyprus is Greek. It used to be the case with Ireland and the UK too

In a lot of cases the links between countries are very strong because in living memory they were the same country. It's not political its just like if England and Scotland put in different songs, both countries would probably know the singer and the song would appeal to both populations
