In August 2014, we see that the year over year growth rate of the goods that the U.S. imports from China decelerated to the lowest level recorded since February 2014, corresponding to the period of negative economic growth that the U.S. economy experienced in the first quarter of 2014.
But at 1.7%, it's not in negative territory, which suggests that economic growth in the U.S. was only sluggish in August 2014. We won't have the official trade data for September 2014 until the U.S. Census Bureau releases it on 14 November 2014. China's officially reported trade data is generally considered to be unreliable.
Looking at the year-over-year growth rate of the value of the goods that China imports from the United States, we see that China's economy also slowed, but is growing more rapidly than the U.S. economy, reversing the situation that existed earlier in the summer.
