CHINESE officials are content with their progress to date in reining in the unruly national economy, and appear to be committed to carrying forward economic reforms, even though they have not set specific timetables, according to organisers of an economic roundtable with Chinese Government representatives. There was ''a sense that government officials are fairly happy with the current slowing down'', said Lois Dougan Tretiak, Vice-President and Director/China for the Economist Conferences, a subsidiary of the London-based Economist Group, which organised the three-day roundtable in Beijing this week. Ms Tretiak said there was no indication that economic reforms were being shelved for the duration of the Government's campaign to check inflation and restore order to the financial system. The conference was attended by more than 120 senior executives representing 79 international corporations, and senior Chinese officials including Vice-President Rong Yiren, and, among others, top officials of the State Economic and Trade Commission, the Securities Regulatory Commission and the Electric Power Ministry. Ms Tretiak said the tone of the meeting was positive, confirming that China was pushing forward with its market reforms. None of the officials spoke negatively about the reform process, or seemed to be putting a damper on the reforms, she said. Indeed, officials did not describe the current government economic policy as a readjustment. Nor did the theme of economic slowdown crop up that much during the discussions. Chinese officials made it clear that they wanted more foreign investment in infrastructure projects, such as power generation and rail, and acknowledged that rates charged to customers for such services would have to rise in order to attract capital fromabroad. Ms Tretiak noted that major investment banks were looking at infrastructure projects in China. ''The interest is out there now,'' she said. As a mark of free market-oriented change, central planners at the conference appeared to be a humble lot who ''were happy to do anything that worked to bring in funds'', said Jeffrey Schultz of the international public relations firm Burson-Marsteller, one of the sponsors of the conference. Officials also noted that new tax legislation designed to make the system simpler and more uniform was now before the State Council. But, foreign businessmen voiced their displeasure with FESCO, an arm of the Chinese Government which has a monopoly on allocating Chinese workers to foreign enterprises based in China. Among the complaints were that FESCO provided unqualified staff with little loyalty to their foreign employers, and that FESCO itself took most of the salaries paid to Chinese staff.
