Just look at source of your article. Dubious at best. Then think about it. If Chinese were duped by the US much more would be made out of this.
Furthermore, WHY does the US even need to fake gold? Gold is heavy and in limited supply. They US could very well just sell Treasuries. I piece of paper IOU for US$1M. I think I personally can carry US$5B worth. On top of that, US can print as much as they want.
When reading an article, always see where it is from. Is it biased? Is it a mainstream outlet? Who is the author? After that think if what is written makes sense. Also, there should usually be correlation and support for the story.
