China's August exports were up 5.5 percent from a year ago in dollar terms, while imports were up 13.3 percent in dollar terms.
China's imports of copper and copper products climbed by 26.5 percent year-on-year in September, Reuters calculations based on customs data showed Friday, but still remain on course for an annual drop in 2017.
The gain was stronger than the most optimistic forecast in a Reuters analysts poll.
The solid September readings will be welcome news for Beijing ahead of a major political leadership reshuffle next week, at which President Xi Jinping is expected to further tighten his grip on power. Estimates, growth in export and import volumes picked up to 6.7% year-on-year and 13.6% respectively. Imports were forecast to jump 13.5 percent in the same period. Copper imports were the highest since March. Exports to the United States were a record $40.9 billion in September, creating a record surplus of $28.1 billion with the country.
The trade surplus was the lowest in six months. "The improvement in September comes even as cooling prices pressures should have weighed on trade values".
