The deal - ICBC's biggest takeover in nearly four years - is expected to cost no more than $650 million, it said in a statement on Wednesday. The two affiliates are asset manager Standard Investments and Inversora Diagnol, a commercial service provider.

Argentina's central bank approved the deal on Nov 8, making ICBC the first Chinese lender to enter Latin America's third-largest economy.

SBA is Argentina's 12th biggest bank by assets. It has a full banking license and its services cover retail, corporate, and investment banking. In 2008, it acquired a 20 percent stake in Standard Bank, Africa's biggest lender by assets.
