BEIJING, Feb. 17 (Xinhua) -- The value of bonds issued in China totaled 2.5 trillion yuan (394.1 billion U.S. dollars) in January, data from the central bank showed.

Of the bonds issued, 2.4 trillion yuan's worth were sold through the inter-bank bond market, while treasury bond issuance stood at 190 billion yuan, according to the People's Bank of China (PBOC).

By the end of last month, the size of outstanding bond market debt came in at 75.1 trillion yuan.

A number of regulations were introduced last year to rein in financial risks with mounting local government debt.

The central bank has pledged that more efforts will be made to improve disposal of bond defaults, and unify rules on approval and information disclosure of corporate credit bond issuance.

Last year, China issued bonds worth 40.8 trillion yuan, up 12.9 percent year on year, earlier data from the central bank showed.
