China Trade Surplus Reignites Tensions Over the Yuan

China in August posted its third straight trade surplus of more than $20 billion, putting friction with the United States over the nation's currency back in the spotlight. Exports rose 34.4% in August and imports climbed a greater-than-expected 35.2%, leaving the country with a $20.03 billion surplus, a customs bureau report showed Friday. But a sustained trade gap with the United States could embolden American lawmakers who are pushing to penalize China for what they consider unfair trade practices.
