Mr. Tingxiu Lu, Chairman and CEO of China Sunergy, commented: “I am delighted that Allen Wang has decided to join us and look forward to working closely with him over the coming months. I was particularly impressed by both his drive and ability to grasp the more technical element of our business and believe that these factors, combined with his considerable operational experience and proven ability to grow a business, will be of enormous benefit to us as we seek to forge closer ties with suppliers and expand our operations.”

Mr. Wang further added: “It is a great honor to be appointed to be the CEO of such a young and dynamic company as China Sunergy. As an engineer, I am extremely impressed by the strength of the company’s research and development efforts and look forward to ensuring that these efforts can be commercially realized as we seek to expand our customer base and secure long-term contracts with our suppliers.”
