The Industrial and Commercial Bank of China (Asia) is busy integrating two acquisitions it made last year. Managing director and chief executive Zhu Qi said ICBC (Asia) had plans for the Hong Kong unit of Fortis Bank, which now operates as Belgian Bank, and Shenzhen's Chinese Mercantile Bank (CMB). 'Retail banking has been our core business,' Mr Zhu said. 'There are many Hong Kong small and medium enterprises doing business in the mainland, and Belgian Bank is very strong in this area.' He said it was hoped that CMB would provide a point from which to grow when ICBC (Asia) extended its services to the Pearl River Delta. Mr Zhu was pleased with the performance of Belgian Bank, which contributed more than 30 per cent of ICBC's total profit in the first six months. ICBC (Asia) posted a 33 per cent rise in interim net profit to $475.55 million.
