Customer satisfaction with retail banks in China has improved this year due to the industry's efforts in creating transparency, according to a survey released by JD Power Asia Pacific Inc on Monday.

Overall satisfaction in 2013 improved by 74 points to 761 on a 1,000-point scale from 2012, after having experienced a two-point increase one year earlier, the company said.

"The dramatic improvement in customer satisfaction is attributed to the concerted efforts across the industry in creating transparency and improving the customer experience," said Steven Zou, director of financial services at the company.
