The Industrial and Commercial Bank of China (ICBC) said on Thursday it had agreed to buy 1.92 billion HK dollars ($246 million) worth of shares and warrants of its Hong Kong unit -- ICBC (Asia) Limited -- from the Spanish Fortis Bank.

The deal, if completed, would raise the stake of ICBC in its Hong Kong unit from the previous 62.98 percent to 71.21 percent, the country's largest commercial lender said in a statement released here.

The purchase included an 8.23-percent stake in the common shares of ICBC (Asia) Limited held by Fortis Bank.

ICBC (Asia) Limited was the flagship subsidiary in charge of ICBC's overseas business. It had become the sixth-largest bank, asset-wise, in Hong Kong by the end of June with assets totaling 224.8 billion HK dollars.

"The purchase of the stake from Fortis demonstrated ICBC's confidence in the future prospects of its Hong Kong unit as well as the financial market in Hong Kong," said ICBC's President Jiang Jianqing.

The deal was still subject to approval of the China Banking Regulatory Commission and related departments.
