Yes, Russia has really been adding to its gold stocks in recent years (I don't know to what extent from its own production). They probably cant lose by doing so, as it is a great devaluation hedge on their shaky currency. China also, but purchases there have been as much private as government (if you can separate the two). Both countries are buying less than they themselves produce from their mines each year (to keep it in perspective). China is the world's largest producer, Russia the ?fourth largest (Australia and the USA being the other two).
Seems to me there are two issues with gold. The first is speculation on the price, which is little more than gambling day to day. The second is the real one - protection against massive devaluation of currencies, economic crises. We all know there is a crunch coming and some economists speculate that it could exceed the GFC. I am happy to hold some gold as part of a balanced portfolio - so long as you are in no danger of HAVING to sell, and can sit on it as security..
