Very likely. China have been playing a long and patient game building up their sovereign wealth and moving away from the USD standard. The Chinese history is long and proud, they were once the most powerful nation and biggest economy on earth that they sure haven't forgotten about. They are thinking long long term and I believe working their way back to the glory days of the Silver Empire. Gold and Silver = Power and they know this. The Chinese people have been buying up gold big time since The Chinese government lifted the ban (in 2004 from memory) and the Gov have actually been promoting it to their citizens. The Chinese don't have trust in paper money as they've learnt from history, metals they trust. Who knows how much the Gov hold as the biggest producer in the world and one of the biggest importers, plus their citizens have also been hoarding for a long time.
Russia under Putin have also built up their sovereign wealth and actually have the second most gold in the European region behind Sweden, quite a feat from 25 years. Putin's greatest legacy will be restoring Russia's sovereign wealth through a long and steady gold hoard that they physically hold.
If you think this fiat system will be around forever you're dreaming. It's a question of when and these countries have a lot more patience then any stacker or investor
