Bank of China Ltd planned to sell its first Dim Sum bond in almost two years on Monday, according to a person familiar with the matter.

The mainland's fourth-largest lender by market capitalization is marketing a sale of as much as 1 billion yuan ($156.8 million) of three-year notes in Hong Kong, the person said, asking not to be identified because the details are private. It is offering the debt to investors to yield 3.1 percent to 3.2 percent, according to the person.

Bank of China last sold Dim Sum bonds in September 2010, when it offered 5 billion yuan of the securities, according to data compiled by Bloomberg. The 2.2 billion yuan two-year portion of the notes matures this year, the data show.
