I also hear that they go over it by using third nations instead. So Russia sells something to X nation, then X nation sells that to Germany, that way Germany still buys from Russia, the only difference is that X nation makes money in the middle instead. Makes things more expensive for Germany to buy, and makes things cheaper for Russia to sell, because that difference will go to X nation instead.
However, that still doesn't mean that sanctions work, it just doesn't work for either, not for Europe, not for Russia, both are still dealing with each other. When you combine all the ways sanctions are broken there isn't really all that much that still stays unused, it is trading and all nations are dealing with each other aside from maybe a few products.
I didn't mean your example but that's true and I don't see any point in that. They sanction Russia but then buy from the middleman which results in significantly expensive prices and problematic delivery. You have a pipeline with Russia, just get gas through it, what's the point of a middleman buying it for you from Russia, and then delivering it to you? I don't know. It's not a boycott, it's something else.
My country for example, took the advantage of this situation and many rich Russian people flew here, started businesses, are paying enormously high money in rent, our local currency became very stable because of the dollars that they bought with them when they came here. I know that long-term, it will be devastating because Russians are massively buying houses, getting citizenship, investing money in businesses and acquiring them. Soon we will be the work class and they'll be business owners and landlords here.
This war is not doing any good to anyone.
