Can China afford its aging population?

Recently released figures for China show that, as of the end of last year, there was1.95 trillion yuan in the country's pension fund. The glowing report indicated the fund grew more quickly in 2011, at almost 26 percent, than the number of retiring seniors who needed it, which grew at less than 21 percent. So far, so good, but if China follows the pattern we've seen in the West, there could be dark clouds ahead.
