(Bloomberg) -- Hong Kong’s benchmark Hang Seng Index bid farewell to local lender Bank of East Asia Ltd. and terminal operator China Merchants Port Holdings Co. in the latest review.

The two stocks in the 50-member index will be replaced by Sino Biopharmaceutical Ltd., only the second biotech firm to join, and textiles manufacturer Shenzhou International Group Holdings Ltd., the Hang Seng Indexes Co. said in an emailed release Friday. The changes will take effect Sept. 10.

There is no change in the Hang Seng China Enterprises Index.
