President Obama has spent 43 months failing to confront China's unfair trade practices. Campaign-season trade cases may sound good on the stump, but it is too little, too late for American businesses and middle-class families. President Obama's credibility on this issue has long since vanished. I will not wait until the last months of my presidency to stand up to China, or do so only when votes are at stake. From Day One, I will pursue a comprehensive strategy to confront China's unfair trade practices and ensure a level playing field where our businesses can compete and win.
