But international doubt lingers over China's response to Sars China has reinforced its call for an international fund to finance global efforts to curb the spread of Sars. The call by Vice-Premier Wu Yi in Geneva came after she revealed that the central government would make its biggest single investment in the health-care system - a centre for disease control in Beijing costing 8 billion yuan (HK$7.5 billion). According to Ms Wu, the new facility will be completed before 2008 - the year Beijing holds the summer Olympics. The central government has been criticised for failing to address the problem of Sars when it first broke out in the country and for covering up past major outbreaks. Addressing the World Health Assembly in Geneva, Ms Wu admitted that the government had made mistakes in handling Sars. 'There are shortcomings in our public health system - officials were not organised, communication channels unclear,' she said. 'Moreover, some of our [government] units simply have failed in their endeavour. At one point, our efforts to control the disease were reactive and passive.' But Ms Wu vowed to address these issues and demanded timely reporting from local governments. '[We will not tolerate] late reporting, misreporting or even cover-ups by any localities and work units,' she said. 'All units must strive for early diagnosis, early reporting and early medical treatment.' Ms Wu repeated an earlier offer to contribute to an international fund on Sars. Premier Wen Jiabao pledged 10 million yuan late last month when he attended an Asean summit in Bangkok. But the offer has not been met with much response from other nations. Timothy Wong Ka-ying, director of the Telephone Survey Research Laboratory of the Hong Kong Institute of Asia-Pacific Studies at the Chinese University, said the vice-premier's pledges alone could not restore the international trust in China. 'The pledge of setting up an international fund and disease control centre indicates China's eagerness to clear other countries' doubts,' Dr Wong said. 'But whether the trust can be restored does not rely on one simple action.' Dr Wong said further moves to limit the outbreak would bring China's policy on Sars more in line with the WHO's requirements. But it was not an easy task and it would take months before the international community's doubts over China's response could be overcome.
