Spain, Netherlands and Belgium have large port facilities for oil and gas throughput. My guess what is likely happening is that goods get transported further into the remaining EU states but are not officially registered as sourced from Russia, creating a semi-black market. That, plus filling the national gas reserves, has driven up imports.

I wouldn't look into it too much. If we get an oil pricecap and maybe also a soft winter the values of Russian imports will plummit.

Most countries have little to no reason to care more about Ukraine than they care about Yemen. Yemen is a longer lasting and more bloody conflict where Saudi Arabia is trying to install a puppet regime but nobody really gives a fuck and nobody is sanctioning Saudi Arabia because it is too important to sanction.

It's not about whether countries have a conscience. Countries are not persons. It all depends on what type of goods the trade with certain countries is focussed on, in what way these goods are affected by the sanctions and what type of wiggle room individual companies in these countries have and what risk they are willing to take. And here the ownership structure of the companies plays a role, too.

In general one should not read too much into such a diagram. There is a real problem only if the sanctions are circumvented. And, of course, maybe it shows that we should extend the sanctions to other type of goods.

countries don't have conscience, countries have interests. as soon as you start shifting your mentality towards that, you'll get a wider mental picture of international relations
