The development in the field of health services has brought concrete benefits to the Chinese people. The average life expectancy of the Chinese rose to 76.5 years in 2016 from 67.9 years in 1981; maternal mortality dropped from 88.9 per 100,000 persons in 1990 to 19.9 per 100,000 persons in 2016; and infant mortality declined from 34.7 per 1,000 in 1981 to 7.5 per 1,000 in 2016. The main health indicators of the Chinese are generally better than the average level of middle-and high-income countries, and China has achieved the UN's Millennium Goals in this regard ahead of schedule. Furthermore, China has established a complete medical and health system that is guided by the Constitution, based on civil laws and regulations, laws and administrative regulations on health, and local regulations, and directed by the outlines, programs, and plans of the health sector. The system has proved effective in maintaining sound doctor-patient relations, addressing medical disputes with impartiality, and ensuring citizens' right to health.
