https://en.wikipedia.org/wiki/Refugees_of_the_Syrian_Civil_W.... Saudi Arabia is the 6th country. UAE 10th, Kuwait 11th, Egypt 12th. Sweden is 13th. Germany is the only rich european country in higher positions, and it's the fourth one.
Why don't they go to China, Japan, Russia, Kenya or New Zealand? Well, just look at a map. Syria -> Greece can be a long but doable journey. Except Russia (and that would be entering via Georgia, which doesn't seem to be like an easy route) all of those are pretty unfeasible.
About the figures, yes, they're not the best but they're an indicator and probably useful for comparison. And they do not confirm that immigration is higher in NWE. Sweden and Belgium have far less population than Spain (~10 vs 45 millions). If you add immigration percentages in France, Portugal and Italy, I'm pretty sure that it's not higher, and even if it is, it wouldn't be by much.
> The problem is that this is happening in a few decades time. In countries that have never seen immigration and were screwing it up big time long before the Syrian refugee crisis.
So what's the solution? Sweeping the problem under the rug? Because it's not an impossible task. It can be done. Spain has received a huge amount of immigrants in the last decade (2000 it was 2%, 2010 was 12%). The fact that a lot of them were spanish-speakers helped a lot, but you don't either see problems with the muslim population (12% of the foreign population is Moroccan, for example).
