MANAGEMENT consultancy services will be in great demand when China's economic structure moves from planning to become more market-oriented, says management consultant K.K. Yeung. Mr Yeung, who runs K.K. Yeung Management Consultants, said mainland enterprises were plagued by problems during the change-over. ''Mainland companies now very much need corporate rescues in order to reinforce their profitability and to enable a better cash flow,'' he said. Help could come in the form of financial management, asset management and engineering support. The modernisation of mainland enterprises has also led to foreigners setting up joint ventures, which are the target customers of Mr Yeung's company. ''The lack of information flow has frustrated foreign investors aiming to open up the China market,'' Mr Yeung said. ''Normally, it will take an outsider a lot of time and money to investigate the investment environment on the mainland.'' Good information channel and networking was very important to get things done in China. ''What makes things worse is that most foreign investors do not take China long term.'' In June, Mr Yeung's company signed an agreement with a Shanghai partner to help foreign investors in China and to act as trouble-shooter for joint ventures set up by foreigners. Mr Yeung said the Shanghai partner, Shanghai Centre of Scientific and Technological Exchange with Foreign Countries, could provide manpower for projects. The team-up follows the company's joint effort in 1988 with the Beijing International Trust and Investment Corp (BITIC) and Internationale Nederlanden Bank for a similar venture. K.K. Yeung and the Dutch-based bank each has a 35 per cent holding in the venture, with BITIC taking the remaining 30 per cent. Similar liaison offices had also been established in Shenzhen and Guangzhou, Mr Yeung said. ''As a management consultancy company, we'll help our customers mainly in two aspect: business management and cost improvement,'' he said. ''By business management, we'll try to strengthen our revenue and assess the company's technical competence, that is, what it should do and what it shouldn't. ''On cost improvement, we'll help to reduce a company's local cost and overseas costs.''
