Why have cities formed in East Asia?

Cities in East Asia have formed due to a combination of historical, economic, and geographical factors. The region's fertile river valleys, such as those of the Yangtze and Yellow Rivers, supported agriculture, enabling population growth and settlement. Additionally, industrialization in the 20th century attracted rural populations to urban areas for job opportunities, further accelerating urbanization. Strategic locations for trade and commerce, alongside government policies promoting urban development, have also played significant roles in the growth of cities in East Asia.
