--File--People visit the stand of Suntech during the 7th AsiaSolar Photovoltaic Industry Exhibition 2012 in Shanghai, China, 21 March 2012. A major lender to Chinas Suntech Power Holdings, a solar panel maker stung by a US$690 million fraud linked to its expansion in Italy, financed the expansion despite warnings from a business ally to avoid Italys scam-ridden solar sector. US-listed Suntech, the worlds largest supplier of solar panels, has lost 40 percent of its market value since revealing on July 30 that 560 million euros (US$691 million) in bonds involved in securing the bank financing may never have existed. Suntech has declined to discuss how the German government bonds in its possession turned out to be apparent forgeries and has hired lawyers to investigate one of the biggest suspected frauds to hit a listed Chinese company. Sino-Italian private equity firm Mandarin Capital Partners said it wrote emails to the China Development Bank as early as three years ago, advising it not to get involved in Suntechs target area of southern Italy, partly because fraudsters in the booming renewable energy industry there had become a major risk.
