The gold Russia is taking belongs to the sovereign country which it came. It is international law that any precious gem or commodity without paying fees to the government is smuggled. In many cases, such as Somalia and countries like Mali that gold is part of sovereign wealth that can be assessed by the World Bank.
In many instances it is illegal to remove gold from a country. This gold in Africa is not like mining gold in Alaska. Finders’ keepers. This gold belongs to the citizens of that country in Africa.
So, now Russia has and is committing genocide, it is illegally smuggling commodities as well. Whomever is receiving those commodities are as much a criminal as those that stole it.
