BEIJING, Oct. 13 (Reuters) - China’s trade surplus with the United States stood at $30.75 billion in September, Reuters calculations based on Chinese customs data showed on Tuesday, down from a $34.24 billion surplus a month earlier.

For the first nine months of the year, China’s trade surplus with the United States totalled $218.57 billion.

China is still far behind its commitment to purchase more U.S. goods promised in its Phase 1 deal made with the United States. U.S. Department of Agriculture Secretary Perdue said earlier this month that China may fail its commitment on buying enough agricultural products due to “non-agricultural trade issues”.
