China's Ministry of Finance (MOF) said on Monday that it would float 40 billion yuan (US$5.88 billion) of certificate T-bonds, the fourth group this year, from Sept. 13 to 27.

The bonds include 20 billion yuan of one-year bonds with a fixed annual interest rate of 2.6 percent and 20 billion yuan of three-year bonds with an annual interest rate of 3.73 percent, according to a statement on the ministry's website.

Interest will be calculated from the day of purchase, and principal and interest will be paid upon maturity, the ministry said.
