The US Treasury Dept has declared in its report to Congress on international economic and exchange rate policies that Chinese policies dangerously distort the global economic playing field. To wit:
"Current Chinese policies," the Treasury Department said in a report to Congress on Tuesday, "are highly distortionary and pose a risk to China's economy, its trading partners and global economic growth."

Substitute "America" for "China" in that sentence and you have a more accurate characterization of what's going on in the global economy. Amazingly, the US appears particularly exercised about China's holding of $600 billion in US Treasury securities - which, of course, is what underpins the financial solvency of the American government and economy. If China starts to sell those securities, the dollar will plummet, the US will be unable to finance its $600+ billion current-account deficit, and the world economy will face a significant likelihood of what economists like to call a "hard landing".
So what exactly is Treasury trying to accomplish here? Probably just paving the way for some protectionist anti-dumping measures against Chinese exports. Same old same old.
