China's Ministry of Finance (MOF) said Wednesday it would issue this week 27.31 billion yuan (4 billion U.S. dollars) of book-entry treasury bonds, the fourth batch this year.

The issue period would run from April 2 to 6, said the ministry in a statement on its website.

The bonds, with a term of five years, have an annual interest rate of 2.29 percent.

The interest would be calculated from the day of purchase and paid annually. Principal will be paid on April 2, 2014, according to the statement.

China has increased its issues of treasury bonds to finance its4-trillion-yuan stimulus package for the next two years, with the central government to spend 1.18 trillion yuan.

The MOF said the nation would issue ten batches of book-entry treasury bonds altogether in the second quarter.
