China's newly-issued 25 billion yuan ($3.6 billion) worth of central bank bills in the Hong Kong Special Administrative Region on Tuesday were 2.8 times oversubscribed, reflecting continued interest in yuan-denominated assets by global investors.

The issuance included three-month bills of ten billion yuan and one-year bills of 15 billion yuan, with interest rates of 2.4 percent and 2.75 percent, respectively.

The total amount of bids by overseas investors exceeded 70 billion yuan, indicating confidence in the Chinese economy, said the People's Bank of China in a notice.
