The Agricultural Development Bank of China, one of the country's three policy banks, saw its net profit up 7.5 percent year-on-year to 15.2 billion yuan ($2.5 billion) in 2014, the bank's governor Zheng Hui said on Tuesday.

Its operating profit last year came in at 50.56 billion yuan, according to Zheng, while the non-performing loan ratio of the bank settled at 0.57 percent, down 0.14 percentage points from the rate seen a year earlier.

As the sole agriculture policy lender in China, the bank said it has stepped up support to the sector in 2014.

Its outstanding loans for agriculture support totaled around 2.6 trillion yuan as of the end of 2014, accounting for over 90 percent of its overall loans.
