The Ministry of Labor and Social Security set China's first minimum wage law on 1 March 2004. The Regulations on Enterprises Minimum Wage was made to "ensure the basic needs of the worker and his family, to help improve workers' performance and to promote fair competition between enterprises." One monthly minimum wage was set for full-time workers, and one hourly minimum wage for part-time workers. Provinces, municipalities, and autonomous regions are allowed to legislate for their own minimum wage separate from the national one.
In February 2010, officials in Jiangsu province increased the minimum wage to 960 RMB (about US$140.62) per month, the same as Shanghai. China's highest minimum wage is in Shenzhen (1000 RMB per month).
Guangdong Province increased its minimum wage on 1 September 2006 and was split into five categories. The highest is ¥780 per month or ¥4.66 (~US$0.68) an hour (in Guangzhou city). The lowest is ¥450 per month or ¥2.69 (~US$0.39) an hour.
