The fraud trial for former Anbang Insurance Group Chairman, Wu Xiaohui, began Wednesday in Shanghai. He's charged with illegal fundraising, fraud and embezzlement. A month ago the government seized his company and announced Wu was being prosecuted. Anbang had been one of the most aggressive investors in a wave of overseas acquisitions by Chinese firms. Founded in 2004, Anbang grew from selling car insurance into one of China's largest companies - with more than 800-billion yuan in assets. Now, China faces an escalating fight to rein in the spiralling debt of big-spending conglomerates.
