Feb 12 (Reuters) - Chinese authorities are exploring a plan to help China Vanke plug a funding gap of about 50 billion yuan ($6.84 billion) this year, which will aid the property developer to repay its public and private debt, Bloomberg News reported on Wednesday.

As part of the proposal, regulators will allocate 20 billion yuan in special local government bonds to buy unsold properties and vacant land from Vanke, the report added, citing people familiar with the matter.

Vanke and its affiliates will also be allowed to tap other financing sources including new bond sales and bank loans for debt payments, Bloomberg said, adding that details of the plan could still change.

Shares of the company, which is grappling with a liquidity crisis and sluggish sales due to China's ailing property sector, rose more than 16% in Hong Kong trading. Country Garden also up 8.8%, Sunac up 20%, Shimao up 16%. Fangdd up 21% and Ke Holdings up 7% in overnight trading.

China Vanke said in a statement it will "go all out" to raise funds through operations and financing for the public bond obligations due in 2025. It also said it would continue to accelerate asset sales and exit its non-core businesses for the repayments.
