China's economic tightening measures are working, Premier Wen Jiabao told the sixth Asia-Europe working meeting in Helsinski. Without revealing figures, Wen said industrial output and fixed-asset investment may have started to slow down in the last month, the Financial Times reported. According to government statistics fixed asset investment jumped 30.5% in the first seven months of 2006. But the consumer price index has remained at a relatively lower level, said Wen, suggesting this showed the latest macroeconomic controls have been a success. Still, further effort is required to cut down on energy consumption and save energy, Wen observed.
