The Coalition for a Prosperous America has filed comments with the U.S. Trade Representative’s Office in support of their investigation into Vietnam’s currency undervaluation. CPA CEO Michael Stumo says Vietnam’s currency is undervalued by 15 percent creating an unfair trade advantage for them.

He says the USTR needs to put duties on Vietnam because of not only the loss value in exports but also in lost jobs.

Stumo says manipulation of currency hurts agricultural exports the most.

In their letter to the USTR, the CPA noted that Vietnam now accounts for roughly 10 percent of America’s global trade deficit.
