China and Dubai are both significant global economic hubs, but when comparing their levels of development, China surpasses Dubai in several key aspects. China, as the world's second-largest economy, boasts a diverse and robust economic structure, while Dubai, though a prominent city-state in the UAE, is more focused on certain sectors like tourism and finance.

China's development is more comprehensive, encompassing industrial, agricultural, and service sectors. According to the World Bank, China's GDP per capita was $11,895 in 2021, reflecting a significant increase from $1,020 in 2000. This growth has been driven by a combination of factors, including China's vast labor force, technological advancements, and infrastructure development. China's infrastructure, including its extensive high-speed rail network and the world's largest 5G network, is a testament to its development.

Dubai, on the other hand, has made remarkable strides in certain sectors, particularly in tourism and real estate. The city has become a global hub for luxury tourism, with iconic landmarks like the Burj Khalifa and the Palm Jumeirah. However, Dubai's GDP per capita of $42,830 in 2021, while impressive, is significantly lower than China's and does not reflect the same level of economic diversification. Dubai's economy is heavily reliant on oil revenues, although it has been diversifying into other sectors like finance, logistics, and real estate.

Moreover, China's population of over 1.4 billion provides a vast domestic market, which is crucial for economic development. China's urbanization rate, which stood at 63.8% in 2021, has led to significant infrastructure investments and economic growth. In contrast, Dubai's population of around 3.3 million is much smaller, and its economic growth is more dependent on attracting foreign investment and tourists.

In terms of technology and innovation, China is a global leader. It is the world's largest producer of solar panels and has made significant advancements in artificial intelligence and 5G technology. Dubai, while making strides in technology, particularly in smart city initiatives, does not match China's scale and pace of technological innovation.

In conclusion, while Dubai is a highly developed city-state with strengths in tourism and finance, China's overall development, encompassing a diverse economy, a large population, and significant technological advancements, makes it more developed than Dubai.
