Over the past decades, the Chinese Government has spared no effort in this regard and, as a result, the Chinese people's health has significantly improved. In the nationwide fight against the SARS (severe acute respiratory syndrome) epidemic in the first half of 2003, the Government placed the health of the Chinese people and the safety of their lives above everything else. With a huge input of human, financial and material resources, the country won a decisive victory over the epidemic. Following is the full text of an interview by Human Rights with Gao Qiang, executive vice-minister of the Ministry of Health, on China's medical and health work and how it is related to protection of human rights.展开更多
