I don't get the point of this. As the article points out, it would be perfectly legal for Shell to sell refined oil products of 100% Russian origin. Why do they go to the length of blending it to 49.99% Russian origin and expect to get away with calling this "Latvian", in a day and age where far more clandestine operations become public knowledge in practically no time with p>0.99 (remember, Russian troop movements prior to the war were reported practically in real time with satellite imagery, something Putin surely didn't appreciate)?
