HONG KONG, March 28 (Reuters) - China Vanke, China's second-biggest property developer by sales, on Thursday reported 9.8 billion yuan ($1.36 billion) in 2023 core profit which excludes the impact of foreign exchange and changes in the value of assets and financial instruments.

That was down from 19.8 billion yuan a year earlier.

Investors have been dumping shares and bonds of the state-backed developer in the recent weeks due to liquidity concerns.
