en.Wedoany.com Reported - The inauguration ceremony of the Ulaanbaatar Central Wastewater Treatment Plant, constructed by China Railway Group Limited (CREC) Fourth Bureau Group Co., Ltd. (referred to as "China Railway Fourth Bureau"), was held on June 15, 2026, in Ulaanbaatar, the capital of Mongolia. Wang Yi, Member of the Political Bureau of the CPC Central Committee and Minister of Foreign Affairs, jointly attended the event with Uyiles Tuguldur, Head of the Office of the President of Mongolia, and Battsetseg, Minister of Foreign Affairs of Mongolia. This project is the largest and most technologically advanced wastewater treatment facility in Mongolia, with a designed daily treatment capacity of 250,000 cubic meters, serving nearly half of the country's population.
The Ulaanbaatar Central Wastewater Treatment Plant is a key cooperation project between China and Mongolia, constructed using Chinese standards and technology. The project covers a total area of 178,000 square meters and includes 55 individual buildings. Once operational, the plant will collect and treat domestic sewage and industrial wastewater generated in Ulaanbaatar, significantly improving the city's water environment quality and providing crucial ecological infrastructure support for the sustainable development of this city with a population of approximately 1.5 million.
At the inauguration ceremony, Wang Yi stated that this project was one supported during Chinese President Xi Jinping's state visit to Mongolia in 2014. He noted that this livelihood and friendship project, carrying the entrustment of the leaders of both countries and the expectations of their peoples, has transformed from a blueprint into reality, from groundbreaking to completion, becoming another important symbol of mutual assistance between China and Mongolia. Wang Yi emphasized that China has consistently supported Mongolia in developing its economy and improving people's livelihoods. Since the 1950s, Chinese aid workers in Mongolia have helped build over 850 projects. Entering the new century, the areas of cooperation between the two sides have continuously expanded, and China-Mongolia relations are becoming a model of friendly coexistence and common development between neighboring countries.
Uyiles Tuguldur, speaking on behalf of the President of Mongolia, stated that this project is an important achievement of Mongolia-China cooperation and a concrete manifestation of the good-neighborly and friendly relations between the two countries. He expressed gratitude to the Chinese side for its support of Mongolia's economic and social development.
The commencement of the Ulaanbaatar Central Wastewater Treatment Plant represents the latest achievement of pragmatic cooperation between the two countries in the fields of infrastructure construction and livelihood improvement, having a direct and profound impact on enhancing the environmental carrying capacity of Mongolia's capital and the quality of life of its residents.
