The Chinese trade surplus landed at $79.39 billion in August, shrinking compared to last month's $101.26 billion, the country's General Administration of Customs said on Wednesday.
The figure dropped to a three-month low and landed below the forecast of $92.7 billion, disappointing investors' expectations.
Meanwhile, the country's exports increased by 7.1% in dollar terms on an annual basis, with imports rising by 0.3%, both below analysts' projections.
