Explain, with details, what made China a wealthy country.

The answer lies in China’s five-year plans. Inspired by the Soviets, the Chinese focused on heavy industry and slowly developed their economy. With each subsequent five-year plan, the government improved the country’s industrial and service output and liberalized the economy.

Industrial Growth
