Alibaba Group Holding Ltd. plans to sell $7 billion in bonds in the biggest dollar bond sale this year by an Asian corporate issuer.

The Chinese e-commerce giant is offering the notes in five parts, with maturities of 5.5, 10, 20, 30 and 40 years, according to people familiar with the offering, who are not authorized to speak publicly and asked not to be identified.

The bond deal would eclipse China Evergrande Group's $6.6 billion offering in June, the biggest so far this year in Asia from a nonbank issuer, according to data compiled by Bloomberg.
