After years of working in Cambodia, CCCC employee Cai Wen often recalls his first visit to the country. On his way from the airport to the project site, he saw quiet, simple villages along narrow, bumpy and muddy roads, with motorcycles serving as the main means of transportation.

Today, the Phnom Penh-Sihanoukville Expressway, Cambodia's first expressway, built by CCCC, carries a steady stream of traffic, cutting travel time between the capital, Phnom Penh, and the major port city of Sihanoukville from more than five hours to less than two. National highways, including National Roads 55, 10, 3, 31 and 33, have also been upgraded, further improving connectivity and facilitating travel along the routes.

"We are building not only roads that extend in all directions and bridges that span rivers, but also avenues of development that lead local people toward a better life and a brighter future." Through his work, Cai has gained a deeper understanding of the mission and responsibility of infrastructure builders.

During construction, Cai and his team tackled challenges posed by Cambodia's long rainy season by developing sound construction plans and optimizing personnel and equipment shifts, minimizing the impact of the rainy season on construction progress and quality.

The projects have also created jobs and new income opportunities for local communities. In addition to recruiting university graduates and skilled workers, they have employed general laborers and, based on their skills and interests, provided hands-on training through a mentor-apprentice model, passing on construction expertise and management experience. Today, many outstanding local employees have grown into skilled technical specialists and capable managers.
