A stable northern frontier helping safeguard national peace
The Inner Mongolia autonomous region in northern China shares a more than 4,200-kilometer-long border with neighboring countries, thus serving as a strategic shield safeguarding the Chinese capital and national security. It also serves as a frontier for China to connect with Mongolia, reach out to Russia and engage with the wider Eurasian continent. Throughout history, what is now Inner Mongolia has been a strategic region for successive central governments to manage the northern frontier and maintain border stability. It was also a key hub along the ancient Steppe Silk Road and the ancient Tea Road.
Over the centuries, successive dynasties established relay stations, frontier posts and military garrisons in the region, giving rise to a long-standing tradition in which border defense and trade went hand in hand. This historical legacy has provided Inner Mongolia with deep historical and cultural foundations for building a strong northern security barrier for China and developing itself into an important gateway for China's opening-up to the north in the new era.
During the Qin (221-206 BC) and Han (206 BC-AD 220) dynasties, as the Xiongnu nomads rose to prominence on the Mongolian Plateau, the Great Wall was built, commanderies established and troops stationed along the frontier, bringing parts of southern Inner Mongolia into the country's border defense system.
The Yinshan Mountains became a natural barrier against incursions by nomadic groups from the north. Emperor Wu of the Han Dynasty sent generals Wei Qing and Huo Qubing on campaigns against the Xiongnu and recovered the Hetao region. Commanderies were established, while policies of migration, land reclamation and the construction of beacon towers were introduced. These measures combined military defense with frontier governance and turned the grasslands and deserts of the region into the first line of defense protecting the security of the Central Plains.
During the Sui (581-618) and Tang (618-907) dynasties, a unified central government further strengthened its administration of the region. Rather than relying solely on military defense, it adopted policies of accommodation and conciliation toward nomadic groups.
During the reign of Emperor Taizong of the Tang Dynasty, an inclusive approach to ethnic affairs was pursued. The administration established protectorates in the northern frontier and appointed leaders of local tribes as governors or prefects of tributary administrative units. By promoting harmonious coexistence among different ethnic groups, these policies helped lay a foundation for stability in the northern frontier.
The region subsequently enjoyed a period of relative calm, while nomadic peoples moved across the grasslands and maintained extensive exchanges, gradually giving rise to new patterns of interaction, exchange and integration among ethnic groups.
During the Liao (916-1125), Jin (1115-1234) and Yuan (1271-1368) dynasties, the areas south of the Gobi increasingly became part of the core territories of successive dynasties. The Liao Dynasty established a prefecture and combined systems of governance suited to both nomadic and agricultural societies, strengthening the military and administrative framework along the frontier.
In the Yuan Dynasty, the southern Gobi region became a strategic corridor connecting the capital with the north of the Gobi and Central Asia. Through the establishment of relay stations and the strengthening of frontier defenses, the Yuan government further integrated the northern frontier into the central administrative system, breaking down long-standing barriers between the Central Plains and the northern grasslands.
During the Ming (1368-1644) and Qing (1644-1911) dynasties, military garrisons were established and defenses strengthened in southern Inner Mongolia, while the Qing Dynasty introduced the "banner" and "league" system, clearly defining pastoral boundaries and strengthening central control.
It was through centuries of such developments, that Inner Mongolia's role as a strategic shield safeguarding China's northern frontier was firmly established.
At the same time, Inner Mongolia was an important commercial hub connecting China with the Eurasian continent. As early as the Han Dynasty, the Steppe Silk Road began to take shape. The southern Gobi became an important route along its northern branch. Chinese silk, tea and porcelain were transported through the region to the northern steppe, Central Asia and eventually Europe, while horses, furs, cattle, sheep and other goods from the north flowed into the Central Plains. Merchants and camel caravans traveled along these routes, breaking down the isolation between the frontier and the interior.
The Steppe Silk Road reached its peak during the Sui and Tang dynasties. As a key hub on its northern route, the southern Gobi witnessed thriving border trade between the Central Plains and nomadic peoples. These exchanges facilitated not only the movement of goods, but also the spread of culture and technology.
During the Yuan Dynasty, an extensive network of relay stations crisscrossed the steppe, making trade across Eurasia more convenient than ever. Some cities developed into international centers of commerce, where goods from the Central Plains, the Xiyu (western regions) and the northern Gobi converged and circulated. The southern Gobi thus became a vital link connecting the Central Plains with the Eurasian lands to the north.
During the Ming and Qing dynasties, border trade and tea-horse exchanges continued to flourish. Commercial centers emerged, while the ancient Tea Road and camel routes across the steppe formed an extensive network. A tradition of openness and exchange became deeply embedded in the historical fabric of the northern frontier.
After thousands of years of historical development, the Inner Mongolia region's traditional role, as both a security shield on China's northern frontier and a commercial hub connecting Eurasia, is closely aligned with Inner Mongolia's two strategic roles in the new era: building a strong and stable security barrier along China's northern frontier and developing itself into an important gateway for China's opening-up to the north.
In the new era, Inner Mongolia has drawn on the wisdom of its historical experience in frontier governance while integrating it with contemporary governance practices. It has worked to modernize its systems and capacity for governing the northern frontier, giving new vitality to a historical mission that has evolved over thousands of years.
First, by carrying forward the long-standing commitment to safeguarding the frontier, Inner Mongolia has strengthened its sense of responsibility and maintained a firm focus on bottom lines. It has established a comprehensive, multi-level and increasingly intelligent system for maintaining security and stability, protecting every part of China's northern frontier and ensuring that people of all ethnic groups can live and work in peace.
On the one hand, the region has worked to improve a coordinated security and defense system. It has explored distinctive measures such as the emergency response mechanism, and patrol posts in yurts, while expanding the ranks of border guardians.
On the other hand, Inner Mongolia is accelerating the intelligent upgrading of border management. In Sonid Right Banner of Xiliin Gol League, for example, drones are being used for patrols, helping address the shortage of manpower, slow response times and low efficiency associated with traditional patrol methods. The coverage of patrols has increased from 60 percent to 95 percent, while patrol time has been cut by half.
The autonomous region is also using smart technologies to build a modern border defense system. Intelligent border-control platforms, operational command platforms and basic information platforms have been established, integrating data from public security, border defense, emergency response, meteorology and other departments. Information-based capabilities for guarding and managing the border continue to improve, with border security moving from a manpower-intensive approach toward a more technology-driven model.
At border crossings, Inner Mongolia has deepened reforms to facilitate trade and travel. These include one-stop clearance at highway ports, intelligent inspection at railway ports and automated guided vehicle transport. The region has also established joint monitoring mechanisms with neighboring countries for cross-border vector-borne diseases, strengthened cooperation with Mongolia to combat smuggling and built lines of defense covering areas outside the country, border ports and the domestic side.
To promote ethnic unity and advance development in border areas, Inner Mongolia has consistently made the fostering of a strong sense of community for the Chinese nation its central task. The region has established 65 national-level model units for ethnic unity and progress, promoted the use of the standard spoken and written Chinese language, and carried out extensive educational and community activities.
Since the beginning of the 14th Five-Year Plan (2021-25) period, Ulan Muqir art troupes at all levels have staged more than 1,500 performances. They have also provided cultural services at the grassroots level, reaching more than 48 million people. Through culture and the arts, these activities have helped bring people of all ethnic groups together in support of border security and development.
At the same time, Inner Mongolia has promoted industries that can increase incomes and strengthen border communities. All 143 frontier villages have received support through central or regional collective-economy programs, with each village now having an annual collective economic income of more than 100,000 yuan ($14,761.67).
Second, by carrying forward the ancient tradition of openness and connectivity along the Silk Road, Inner Mongolia is making full use of its geographical advantages. Guided by the establishment of the China (Inner Mongolia) Pilot Free Trade Zone, the region is actively integrating into the China-Mongolia-Russia Economic Corridor, upgrading its platforms for opening-up, improving transport and logistics corridors, and creating a more favorable business environment. The aim is to promote high-quality opening-up to the north and strengthen Inner Mongolia's role as a pioneer in China's northern opening-up.
Focusing on major border ports including Manzhouli, Ereenhot, Ganqimaodu, Ceke and Mandula, the region is implementing projects to upgrade port facilities and services. Trade zones have been put into operation at Mandula and Ganqimaodu ports, while construction is accelerating on the China-Mongolia Erenhot-Zamyn-Uud Economic Cooperation Zone and the Manzhouli Industrial Cooperation Park. The comprehensive bonded zones in Hohhot, Ordos and Manzhouli are also being developed to a higher standard.
Construction of all 85 key projects under the region's port upgrading program has begun. The investment of 27.1 million yuan has been allocated to support processing projects in border areas. The Tongliao Bonded Logistics Center has been approved, while the Manzhouli railway port's trade zone has begun operations under customs supervision. Cross-border e-commerce pilot zones are also being launched, further strengthening the capacity of Inner Mongolia's platforms for opening-up.
Inner Mongolia is also improving its land-based transport network. In 2025, freight volume through its land ports reached 132 million metric tons, ranking first among China's land ports for the third consecutive year. The region has thus become an important logistics hub for China's trade with countries to the north.
It has also worked to ensure the efficient passage of China-Europe freight trains. In 2025, Manzhouli Customs supervised 4,867 inbound and outbound China-Europe freight trains, up 11.2 percent year-on-year. Of these, 2,977 were returning trains, an increase of 21 percent, the highest number nationwide. These routes have provided stable and efficient logistics support for trade between China, Europe and countries involved in the Belt and Road Initiative.
Meanwhile, Inner Mongolia continues to advance reforms to facilitate customs clearance, with significantly wider use of automated and intelligent inspection systems. It has pioneered the use of automated guided vehicles or AGVs for cross-border transport, with Ganqimaodu becoming home to China's first dedicated cross-border AGV route.
AGVs at Ganqimaodu and Ceke ports have completed more than 180,000 cross-border trips, transporting more than 12 million tons of coal. Vehicles can pass through checkpoints and complete customs declarations automatically, with transport efficiency more than five times that of conventional trucks. Smart ports have consequently become an important driver of efforts to improve the international business environment across the region.
The quality and scale of Inner Mongolia's open economy have improved together. In 2025, the region's foreign trade totaled 220.6 billion yuan, up 6.4 percent year-on-year, 2.6 percentage points higher than the national growth rate. Inner Mongolia traded with 201 countries and regions, 21 more than the previous year, further expanding its network of international economic and trade partnerships.
History offers lessons for the present. At a new historical starting point, Inner Mongolia is following the historical thread of frontier governance and openness that has run through the region for thousands of years. It is strengthening the country's northern security line while shouldering the responsibility of advancing opening-up and development.
By integrating the wisdom of ancient frontier governance with practices suited to the new era, Inner Mongolia is using a secure and stable northern frontier to safeguard national peace and using increasingly efficient channels of openness to support national development. In serving China's broader strategic interests, the region is writing a new chapter for the northern frontier.
