We have been exporting the equipment of cement manufacturing production line for years, especially to Vietnam. It is one of the key products among our exports for which 8 production lines have been accomplished, including the project for an annual output of cement powder of 250 thousand tons in Vietnam. This was the largest project involving Chinese participation in its construction at that time after our winning of the tender. The project was completed and put to use for production on October 10, 1998, its production ability being expanded to 500 thousand tons per year in 2002. The project has been operating for several years and its owner is quite satisfied.
