On December 19, the groundbreaking ceremony for the phosphate upgrading and 60,000-ton per year MAP fertilizer production project of Vietnam Chemical Group’s DAP Company, which is under the general contracting of China National Chemical Engineering Corporation Donghua, was held in Haiphong City, Vietnam. The first phase of the DAP plant constructed by Donghua Company is Vietnam’s first large-scale DAP facility, enabling the plant to operate stably, continuously, and at optimal capacity. It is hoped that Donghua Company will make full use of its technical and managerial advantages in the phosphate chemicals sector to advance the improvement of phosphoric acid quality as well as the completion and operation of the project for producing 60,000 tons of MAP fertilizer per year, thereby achieving improvements in both social and economic terms. It is also expected that the cooperation between the two parties will continue to deepen and develop steadily over time. The commencement of work marks the official entry of the project into its substantive implementation phase. In the future, Donghua Company will continue to follow the overall requirements set by China National Chemical Engineering Corporation for establishing \"three key platforms and one golden brand\" for international cooperation. By providing high-quality engineering services as a link, it will keep deepening its presence in the Southeast Asian market, contributing to the more effective and substantive development of the Belt and Road Initiative.
