Putting it together: "2002 okru free". "Free" might refer to a free zone or area. In Russian, an economic special zone is called "Специальная экономическая зона" (SEZ) or sometimes "free economic zone" (СЭЗ). "Okru" in Russian contexts could be part of an acronym, maybe "Окрестности" meaning surroundings, but that doesn't fit. Wait, "Okru" might be a misspelling of "Округ" (Okrug), which means district or municipality in Russian. So "2002 okru free" might be referring to a special economic zone established in 2002 by the Russian government.
