Sale of the 5.25% senior perpetual securities will be carried out by subsidiary Hero Asia Investment and will close on 7 December, Longyuan says in a statement.
None of the securities will be sold to the public in Hong Kong, where the company's shares are traded, Longyuan adds.
The company has resorted to the debt issue in response to poor appetite for its planned share placement, according to an investment analyst who does not want to be named because of the sensitive nature of the subject.
