Advocate green travel, CIMT2025 Transportation Guide

The 19th China International Machine Tool Exhibition (CIMT2025) will be grandly held in Beijing from April 21-26. This exhibition is hosted by the China Machine Tool and Tool Industry Association and co organized with China International Exhibition Center Group Co., Ltd. It is the largest professional event for machine tools and tools in the world in the past decade. CIMT2025 will simultaneously use all 17 exhibition halls of the Capital International Convention and Exhibition Center (New China International Exhibition Phase II) and the China International Exhibition Center (Shunyi Hall, New China International Exhibition Phase I), with a total exhibition area of 310000 square meters. More than 2400 exhibitors from 31 countries and regions (including China) will compete on the same stage. It can be imagined that in the face of such a large-scale and far-reaching international event, the traffic pressure around the exhibition hall is self-evident, inevitably causing traffic congestion and parking difficulties. However, Beijing has a strong public transportation network with well connected subway lines. Therefore, the organizers strongly urge exhibitors and visitors to use public transportation to improve travel efficiency and exhibition experience. After multiple negotiations, Beijing will also cooperate with the exhibition to increase subway services and support green travel.
