The Cooperative Global Strategy to marginalize US influence in the world has been in place since, at least, 2003 — following the criminally spurious US attack on Iraq, which killed more than a million innocent civilians and destabilized the entire Middle East.
Most likely, the Strategy to marginalize the US first came into existence in the late 1990s, after the "Project for a New American Century" Neocon manifesto — America's Mein Kampf — was published. I first became aware of the strategy in 2005, working the FOREX trading desk during the Asian and London markets. It was there that I fully understood the extraordinary privilege that a nation has when its currency is the Reserve Currency for world trade. I saw how that privilege could be used and abused to bully the rest of the world both economically and militarily. (Don't even get me started on what the NSA did to the psyche of the world, which thoroughly ended any future the US might have as a global power.)
