ABN Amro Asia Capital Investment has taken a 40 per cent stake in a Hong Kong based e-commerce solution provider. GE ECXpress, whose other shareholder is General Electric subsidiary GE Information Services, provides business to business e-commerce and supply-chain management solutions for domestic and mainland companies. No details were disclosed. 'Although the business to consumer market makes the headlines . . . it is the business to business market in Asia where the real transaction volumes are,' said Marc Staal, chief executive of ABN Amro. Mr Staal said business to business e-commerce fundamentals were stronger despite the mainland's population and potential.
