According to a news report, on June 20, the cross-border rail track connection ceremony at the Mohan Port of the China-Laos Railway was held in Xishuangbanna, Yunnan. As the last section of rail was accurately placed and welded, the railway track standards between China and Southeast Asian countries officially achieved interconnection. The cross-border dedicated rail track connected this time has a total length of 120 kilometers and uniformly adopts the 1435-millimeter international standard gauge, marking that China's cross-border railway construction has entered a new stage of standardization.

To meet the requirements of international logistics for heavy-load, long-distance, and multi-system train operations, cross-border dedicated rails have optimized material formulations and welding processes. They adopt high-strength weathering steel and are processed using fully automatic seamless welding technology, with weld strength equal to that of the base metal, capable of withstanding repeated rolling by 4,000-ton heavy-load trains. Meanwhile, 8 cross-border monitoring stations are set up along the rails, equipped with infrared thermal imagers, vibration sensors and other equipment to realize transnational real-time sharing of rail status. Data shows that since the China-Laos Railway and China-Vietnam Railway adopted unified gauge standards, cross-border cargo transportation no longer requires rail replacement operations, with the transportation time shortened by an average of 30% and logistics costs reduced by 25%. The railway department stated that the interconnection of rail standards has broken the "gauge barrier" in cross-border transportation and built an efficient and convenient steel corridor for trade between China and the ASEAN Free Trade Area.
