Chongqing was separated from Sichuan province and made into a municipality in its own right in March 1997 in order to accelerate its development and subsequently China's relatively poorer western areas (see China Western Development strategy).

Traditionally, due to its geographical remoteness, Chongqing and neighbouring Sichuan have been important military bases in weapons research and development. Chongqing's industries have now diversified but unlike eastern China, its export sector is small due to its inland location. Instead, factories producing local-oriented consumer goods such as processed food, autos, chemicals, textiles, machinery and electronics are common.
Chongqing is China's third largest centre for motor vehicle production and the largest for motorcycles. In 2007, it had an annual output capacity of 1 million automobiles and 8.6 million motorcycles.

Natural resources are also abundant with large deposits of coal, natural gas, and more than 40 kinds of minerals such as strontium and manganese, although the mining sector has been
