U.S. Treasury Secretary Jack Lew says the U.S. will hold China accountable for exchange rate fluctuations that recently sent global finical markets into turmoil. Lew told CNBC China has to understand “there’s an economic and a political reality to things like exchange rates." China's surprise move in early August to let its currency float based on market forces caused a sharp drop in its value, leading to a backlash of concern from U.S. lawmakers. China’s President will visit Washington later this month amid the fresh concerns about Beijing's recent policy moves.
