INTRODUCTION TO THE GENERAL ASSEMBLY
PIARC 2025 World International Symposium on Road Tunnel Technology
The PIARC 2025 World Road Tunnel Technology International Symposium is co-sponsored by the World Road Association (PIARC), China Merchants Bureau Chongqing Transportation Research and Design Institute Co., Ltd. (CMCT), National Highway Tunnel Engineering Research Center (NERCRT), China Highway Society Tunnel Engineering Branch (TEB of CHTS), and International Tunnel and Underground Space Association (ITA). It is the only technical seminar held in China/Asia during the PIARC 2024-2027 work cycle. The theme of this meeting is "'tunnel' through science and technology, 'road' to the future - resilience, wisdom, low-carbon and sustainable development". It sets up rich links such as keynote reports and special seminars to present the latest progress of road tunnel technology in an all-round way. The conference will bring together experts, scholars and industry elites in the field of global road tunnels to discuss the cutting-edge developments of tunnel technology and share innovative achievements and practical experience. We look forward to industry experts gathering in Chongqing for this feast of thought and wisdom!
· World Road Association (PIARC) and Ministry of Transportation and Communications of China

Founded in 1909, the World Road Association (PIARC) is one of the most authoritative and influential international organizations in the global road field. As a non-profit, non-governmental international organization, PIARC specializes in the exchange of information on the planning and management, design and construction, operation, safety and maintenance of road facilities. The association has 127 governmental members worldwide and 1,200 expert members from 142 countries or regions, and has set up 20 technical committees, among which the technical committee for tunnel direction is abbreviated as TC4.4. The main activities organized by PIARC are World Road Congress, Winter Road Congress, technical seminars, etc. The association is also a member of the World Road Association, the World Road Association, the World Road Association and the World Road Association.
In China, the Ministry of Transportation and Communications (MOTC) has unified the management of affairs related to the participation in PIARC activities, including the appointment of Chinese technical committees. The Ministry of Transport and PIARC have co-organized a number of large-scale international conferences to actively publicize and promote the achievements and technical experience of China's highway industry, and at the same time take this opportunity to introduce advanced technology from abroad, which is an important window for foreign cooperation in China's highway field.
With the strong support of the Ministry of Transportation and Communications, Mr. Ding Hao, president of PIARC, as a national technical member of the Technical Committee on Tunnels (TC4.4), put forward a request to the Technical Committee on Tunnels to host the international symposium at the “Start-up Meeting of the 2024-2027 Work Cycle” held in Paris, France, in February of this year, which was approved by the Technical Committee on the spot. PIARC and the Ministry of Transportation and Communications (MOTC) have been working together on the project. After several rounds of communication and negotiation between PIARC and the Ministry of Transportation and Communications (MOTC), CMST's request for organizing the Symposium was finally approved, and CMST became one of the 4 organizers among the 13 applicants.
The PIARC 2025 International Symposium on World Road Tunneling Technology held in China is another important achievement of the long-term friendly cooperation between the two sides, which also reflects the high recognition of PIARC on China's achievements in the field of tunneling technology.

· Building a New Platform for International Exchange and Cooperation in Tunneling

The organization of this PIARC 2025 International Symposium on World Road Tunneling Technology will help China to further play an active role in international road traffic and transportation, promote the strengthening of international cooperation and exchange between China and foreign countries, build a platform for international exchanges and cooperation among industry, academia and research institutes in the field of tunnels, and promote the construction of the discipline of tunnels, technological upgrading and sustainable development in the field of tunnels by means of internationalization. Through in-depth discussions and interactions, the representatives of various countries can discuss the common challenges and problems, seek cooperative solutions, promote cross-border scientific research projects and engineering practices, and have a positive impact on the progress of global tunnel technology and international cooperation.
