Baidu Inc, China's largest search-engine provider, said on Monday that it would launch its Baidu Finance Center on Oct 28, offering a product with China Asset Management Co with an annual rate of return as high as 8 percent. The product will be available to registered users of Baifubao, its online payment platform. There's no minimum requirement for depositors, who can take advantage of real-time redemption. However, industry insiders said an 8-percent annual yield is almost impossible to achieve. Baidu has not explained how the target will be achieved.
