Deng Xiaoping's reforms marked a turning point in China's history, shifting from Maoist policies to market-oriented economics. These changes aimed to modernize China's economy, boost living standards, and open the country to foreign trade and investment. The reforms decollectivized agriculture, established Special Economic Zones, and encouraged private businesses. This led to rapid economic growth, transforming China into a global economic powerhouse. However, it also brought challenges like income inequality and environmental degradation.
