A new center for railway standards and inspection in Laos has been officially inaugurated in Vientiane, the nation's capital. This center is a joint initiative between Southwest Jiaotong University and Laos's Ministry of Public Works and Transport.
Zhu Minhao, the Dean of the Transportation Safety Technology Research Institute at Southwest Jiaotong University, highlighted that the establishment of this center is a crucial platform for the "soft connectivity" of standards. It serves as a significant mechanism to accelerate the alignment of quality infrastructure with partner countries under the Belt and Road Initiative framework.
The center is designed to assist Laos in refining its railway standards system, enhancing its inspection and testing capabilities, and improving railway safety supervision. Within the Regional Comprehensive Economic Partnership (RCEP) framework, it will promote collaborative innovation in national quality infrastructure (NQI), aiming to build a cooperative pathway that integrates standard development, mutual recognition of measurements, and unified inspection and certification. This will create a professional technical support platform for standardizing cooperation on the China-Laos Railway.
An expert from China Railway Eryuan Engineering Group Co., Ltd. (CRECG), who participated in the overall design and technological innovation for the China-Laos Railway, noted that the establishment of this center aligns with Laos's core need for railway industry upgrading. It represents a key strategic move for regional cross-border railway connectivity. The center will not only solidify the technical foundation for the routine, safe, and efficient operation and maintenance of the China-Laos Railway but will also provide standardized technical guidelines and authoritative verification support for the planning, construction, operation, and maintenance systems of Laos's nationwide railway network.
"In simple terms, this technical center is both the cornerstone for ensuring the long-term stable operation of the China-Laos Railway and a support for the construction of Laos's national railway network and regional railway interconnectivity," the expert stated.
Cooperation on railway interconnectivity standards between China and ASEAN nations is also advancing on a broader scale. A professor from the same institute at Southwest Jiaotong University revealed that since 2026, China and ASEAN countries have been promoting railway interconnectivity in four key areas: standard alignment, technological innovation, talent cultivation, and cooperative networks.
The core objective is to deepen coordination and alignment in the rail transit standards sector, thereby facilitating mutual recognition of standards between China and ASEAN in railway construction, operation, maintenance, and logistics intermodal transport, while concurrently nurturing specialized technical professionals in the industry.
"Currently, China is engaged in discussions with ASEAN countries on multiple technical specifications, including those for railway interconnectivity, technical requirements for railway rolling stock wheels, technical requirements for railway fastening connections, and solutions for interconnectivity item coding and traceability," the professor added.
Long-term regional railway interconnectivity has been hampered by barriers such as differing technical specifications and fragmented inspection systems, leading to numerous technical adaptation challenges in cross-border operations. The establishment of the Laos Railway Standards and Inspection Center is a critical step towards addressing these pain points and advancing the integrated layout of regional rail transit standards.
The aforementioned CRECG expert provided an example of the challenges faced during the China-Laos Railway project. The Laos section suffered from a lack of basic geological data, making field surveys extremely difficult. The route traversed sparsely populated areas with harsh natural conditions—intense heat, dense jungles, steep terrain, and weak existing road infrastructure, including approximately 60 kilometers through uninhabited zones. Furthermore, a significant safety risk was posed by numerous unexploded ordnance remnants from past conflicts along the route.
CRECG leveraged China's mature and advanced railway construction technologies, innovating in survey and design methodologies. The team applied cutting-edge information technologies like big data and artificial intelligence and established a comprehensive, multi-dimensional network security protection system.
They overcame key challenges including cross-border railway interconnectivity technology, construction techniques for long-span bridges with high piers, full-section tunnel construction technology in high-salinity rock strata, numerical simulation technology for stormwater flooding in small watersheds lacking data, and supporting eco-environmental protection technologies, resulting in numerous core achievements.
This series of original technological breakthroughs ensured the successful completion and operation of the China-Laos Railway under extremely complex conditions and also laid a solid engineering and technical foundation for the implementation of cross-border railway standardization.
The expert further explained that the overall design of the China-Laos Railway strictly adhered to Chinese railway standards and specifications. It involved the verification of core technical parameters such as the number of main tracks, design speed, limiting gradient, and traction mass, while simultaneously finalizing key overall technical schemes like track connection plans and cross-border customs clearance models. This achieved interconnectivity for vital information including international through waybill data, train formation details, handover documents, cross-border train work plans, and passenger train dispatch orders.
Beyond overcoming complex infrastructure challenges, the long-term operation of this cross-border mainline continues to face practical bottlenecks such as high operational costs, lagging industrial support along the route, and insufficient adaptation for cross-border intermodal transport. These factors constrain the overall efficiency of the China-Laos Railway corridor.
Regarding the current pressures on the sustainable development of the China-Laos Railway, Zhang Ruili from Yunnan University and Xu Zhiliang from the Yunnan Academy of Social Sciences recently discussed the topic, highlighting several key challenges. Firstly, there is significant pressure to achieve financial balance. The Laos section faces high operating costs, partly due to electricity expenses being higher than in China, leading to a higher per-kilometer operating cost. Additionally, commercial development along the railway is insufficient, with the Mohan-Mo'ding Economic Cooperation Zone attracting fewer enterprises than anticipated, slowing industrial introduction.
Secondly, geopolitical pressures have led to multi-year delays in projects like the second phase of the China-Thailand Railway (Nong Khai-Bangkok). Thirdly, there is the pressure of balancing ecological protection with economic development. The railway traverses multiple ecological conservation areas rich in biodiversity, which are ecologically sensitive with limited carrying capacity. Achieving sustainable economic growth while protecting the environment along the route is a major challenge.
To optimize the interconnectivity of the China-Laos Railway, Zhang and Xu proposed several pathways. They suggested upgrading the capacity of the railway's tracks and station infrastructure, including the scientific planning and design of double-tracking on key bottleneck sections like Mohan-Vientiane to enhance clearance capacity. Implementing smart, digital, and intelligent customs clearance systems at ports like Mohan-Mo'ding would improve efficiency.
They also recommended promoting the alignment of technical standards and equipment upgrades. To address issues like gauge differences and insufficient signal system compatibility, deploying variable-gauge freight cars at the Vientiane hub could reduce transloading during cross-border transport. Collaborating with the ASEAN Rail Federation (ARF) to advance the development of a compatible signal system for the China-Laos-Thailand railway network was also proposed.
Finally, they emphasized strengthening the hardware connectivity for multimodal transport along the China-Laos Railway. They suggested drawing on the experience of Chengdu International Railway Port's "single document" system for multimodal transport to overcome the "last mile" challenge, building "seamless" intermodal hubs. Furthermore, deploying a cross-border logistics information platform, inspired by the China-Singapore International Land-Sea Trade Corridor model, would enable real-time sharing of freight status.
In September 2022, Southwest Jiaotong University and Laos's Department of Standardization and Metrology signed a Memorandum of Understanding on Cooperation in Railway Technical Standards and Verification Work, marking the formal commencement of standards cooperation for the China-Laos Railway. The first Lao national railway standard, "Basic Terminology Standard for Railway Engineering," jointly compiled by experts from both countries, was officially released. Subsequently, in June 2025, the "China-ASEAN Railway Interconnectivity Standards Cooperation Alliance" was formally established.
This alliance was jointly initiated and established by Southwest Jiaotong University, the Railway Department of Laos's Ministry of Public Works and Transport, the Department of Standards and Metrology of Laos's Ministry of Industry and Commerce, and the ASEAN National Standardization Cooperation and Exchange Center.
Currently, among ASEAN nations, in addition to Laos, members of the alliance include the Ministry of Public Works and Transport of the Kingdom of Cambodia, PT Kereta Cepat Indonesia China (the Indonesia-China High-Speed Railway Company), the Railway Department of Vietnam's Ministry of Transport, and Ho Chi Minh City University of Transport in Vietnam.
