List of Chinese administrative divisions by area in the context of "Xinjiang Uygur Autonomous Region"

Jiangsu is a coastal province in East China. It is one of the leading provinces in finance, education, technology, and tourism, with its capital in Nanjing. Jiangsu is the third smallest, but the fourth most populous, with a population of 84.75 million, and the most densely populated of the 22 provinces of the People's Republic of China. Jiangsu has the highest GDP per capita and second-highest GDP of Chinese provinces, after Guangdong. Jiangsu borders Shandong in the north, Anhui to the west, and Zhejiang and Shanghai to the south. Jiangsu has a coastline of over 1,000 kilometers (620 mi) along the Yellow Sea, and the Yangtze flows through the southern part of the province.

Since the Sui and Tang dynasties, Jiangsu has been a national economic and commercial center, partly due to the construction of the Grand Canal. Cities such as Nanjing, Suzhou, Wuxi, Changzhou, and Shanghai (separated from Jiangsu in 1927) are all major Chinese economic hubs. Since the initiation of economic reforms in 1990, Jiangsu has become a focal point for economic development. It is widely regarded as one of China's most developed provinces, when measured by its Human Development Index (HDI). Its 2021 nominal GDP per capita reached CN¥137,300 (US$21,287), becoming the first province in China to reach the $20,000 mark.

Xinjiang, officially the Xinjiang Uygur Autonomous Region (XUAR), is an autonomous region of the People's Republic of China (PRC), in the northwest of the country at the crossroads of Central Asia and East Asia. The largest province-level division of China by area and the 8th-largest country subdivision in the world, Xinjiang spans over 1.6 million square kilometres (620,000 sq mi) and has about 25 million inhabitants. Xinjiang borders the countries of Afghanistan, India, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Russia, and Tajikistan. The rugged Karakoram, Kunlun, and Tian Shan mountain ranges occupy much of Xinjiang's borders, as well as its western and southern regions. The Aksai Chin and Trans-Karakoram Tract regions are claimed by India but administered by China. Xinjiang also borders the Tibet Autonomous Region and the provinces of Gansu and Qinghai. The best-known route of the historic Silk Road ran through the territory from the east to its northwestern border.

High mountain ranges divide Xinjiang into the Dzungarian Basin (Dzungaria) in the north and the Tarim Basin in the south. Only about 9.7% of Xinjiang's land area is fit for human habitation. It is home to a number of ethnic groups, including the Han Chinese, Hui, Kazakhs, Kyrgyz, Mongols, Russians, Sibe, Tajiks (Pamiris), Tibetans, and Uyghurs. There are more than a dozen autonomous prefectures and counties for minorities in Xinjiang. Many older English-language reference works call the area Chinese Turkestan, Chinese Turkistan, East Turkestan or East Turkistan.

Guangdong is a coastal province in South China, on the north shore of the South China Sea with Guangzhou as the capital. With a population of 127.06 million (as of 2023) across a total area of about 179,800 km (69,400 sq mi), Guangdong is China's most populous province and its 15th-largest by area, as well as the third-most populous country subdivision in the world.

Guangdong's economy is the largest of any provincial-level division in China, with a GDP of CN¥14.16 trillion (US$2.0 trillion in GDP nominal) in 2024, contributing approximately 10.5 percent of mainland China's economic output. It has a diversified economy, and was known as the starting point of ancient China's Maritime Silk Road. It is home to the production facilities and offices of a wide-ranging set of Chinese and foreign corporations. Guangdong has benefited from its proximity to the financial hub of Hong Kong, which it borders to the south. Guangdong also hosts the largest import and export fair in China, the Canton Fair, in Guangzhou. The Pearl River Delta Economic Zone, a Chinese megalopolis, is a core for high tech, manufacturing and international trade. In this zone are two of the four top Chinese cities and the top two Chinese prefecture-level cities by GDP: Guangzhou and Shenzhen, the first special economic zone in the country. These two are among China's most populous and important cities, and have become two of the world's most populous megacities and leading financial centres in the Asia–Pacific region.

Heilongjiang is a province in northeast China. It is the northernmost and easternmost province of the country and contains China's northernmost point (in Mohe City along the Amur) and easternmost point (at the confluence of the Amur and Ussuri rivers).

The province is bordered by Jilin to the south and Inner Mongolia to the west. It also shares a border with Russia (Amur Oblast, Jewish Autonomous Oblast, Khabarovsk Krai, Primorsky Krai and Zabaykalsky Krai) to the north and east. The capital and the largest city of the province is Harbin. Among Chinese provincial-level administrative divisions, Heilongjiang is the sixth-largest by total area, the 20th-most populous, and the second-poorest by GDP per capita after only Gansu province.
