SHANGHAI, People's Republic of China - China just posted its first monthly trade deficit in nearly six years, a $7.24 billion shortfall for March that essentially torpedoes Washington's argument that the Asian giant is a "currency manipulator" of the worst kind.

The Obama administration's assertion that China is artificially keeping the yuan undervalued to gain a global competitive advantage isn't just misguided: It actually demonstrates that Washington lacks even a basic understanding of global economics. Given that the same U.S. leaders who have been pushing to hang this manipulator label on China and impose sanctions are the same ones who tried to end the financial crisis by creating a river of debt that will haunt us for years, I can't say that I'm surprised.

As the U.S. argument goes, pegging its currency to the dollar gives China a distinct advantage when it comes to less-expensive manufacturing and a strong export market. The implication is that somehow this is negatively impacting our economy, or - in a variation of the same logic - holding back our recovery. Washington points to the massive trade deficits we regularly run with that country as evidence of China's currency-market wrongdoing.

In reality, China's pegged currency has done two things. First, it's allowed the United States to keep its inflation rate at a much lower (and more-manageable) level than it should have been in view of the $14 trillion in debt that this country has taken on.

And, second, it's allowed China to fuel its own stimulus package while at the same time assuming a meaningful role in the ongoing global recovery.

Let's take a minute to talk about why this is true.
