Due to China's massive trade surplus over the U.S., China can't keep up with the magnitude of Trump's levies — Beijing doesn't buy enough American products on which to impose the equivalent volume of tariffs in the first place. In 2013, China sold $506 billion worth of goods to the U.S., while importing just $130 billion in American goods.
Trump has said he's ready to erect tariffs on all $506 billion worth of Chinese imports to the U.S. So far, Washington has slapped duties on $50 billion worth of Chinese goods, and a fresh $200 billion more could be facing the same fate this month. In turn, China has imposed tariffs on $50 billion of U.S. goods and threatened another $60 billion following Trump's latest volley, indicating it's not willing to give in any time soon. But its remaining options for retaliation could backfire on its own growth.
