China posted a record $14.5 billion trade surplus in June as exports surged, reported by Bloomberg.   The Beijing-based Ministry of Commerce released a trade surplus widened from $13 billion in May on its website. It was bigger than the $12.8 billion median forecast of 26 economists surveyed earlier by Bloomberg News. The surplus in China, the world's fastest-growing major economy, reached $61.5 billion in the first half, up from $39.66 billion the same period last year. Exports climbed 23.3 percent last month from year earlier to $81.3 billion, and imports gained 18.9 percent to $66.8 billion.
