Legislation to pressure China on its undervalued exchange rate is  wending its way through the Senate this week. Addressing China’s  undervalued currency would be a good thing: China’s exchange rate  policies are partially to blame for the United States’ growing trade  deficit, erosion of jobs providing middle-class livelihoods, and  international financial imbalances that threaten to destabilize the  world economy—and China’s economy, too. Policymakers should not pretend,  however, that tackling the exchange rate issue will be a panacea for  our economic growth, jobs, and competitiveness challenges.
China’s undervalued exchange rate policy in effect subsidizes its  exports, while at the same time making exports from the United States  that much more expensive in terms of China’s money, the renminbi  (sometimes referred to as yuan). But China’s economic modernization and  transformation from an inefficient agricultural producer to a nimble,  technologically advancing, and globally competitive manufacturing  economy rests on a much broader foundation of national economic strategy  than just its exchange rate management.
China is making massive public investments in modern infrastructure  and renewable energy systems, science and technology, education, and  (more recently) social protection. The United States used to know such  public policies are critical in providing a foundation for robust  private-sector economic growth, and could do these things again today  irrespective of China’s exchange rate—were it not for obstructionist  politics in Congress.
