During the full year period of 2011, the Chinese largest lender net interest income, which accounted for 99% of its operating income, rose by 33% to CNY116.46bn ($18bn).

The bank said that it could not achieve net profit as other state run banks, due to government’s backed projects which generated lower interest income for the bank.

During the financial year 2011, its non- performing loan ratio declined by 0.28% point to 0.4%, while the bank’s capital adequacy ratio reduced to 10.78% from 10.87%.

According to the data released by China’s banking regulator, Chinese banks reported a combined net profit of CNY1.25 trillion last year, up by 40% compared to the same period last fiscal.

China Development Bank’s annual report showed that its outstanding loans to the national railway network summed up CNY348.9bn ($55bn) as at the end of 2011.
