Datang International Power Co, the second-largest listed power company in China, said Monday that its plans to sell US$437 million worth of corporate bonds had been approved, Reuters reported, citing the Shanghai Securities News. The issuance is the first batch in a planned bond sale of US$874 million by Datang.

The bonds will be listed on the Shanghai Stock exchange, and should be floated within six months of approval.
