As of the end of August 2025, the 100,000-ton/year polysilicon project in the Sultan Qaboos Free Zone (Suhar) in Oman – the first large-scale photovoltaic industry chain manufacturing project in the Middle East, North Africa, and Africa – which was constructed by China National Chemical Sixth Construction Engineering Corporation, has entered the final stages of installation, pressure testing, and purging. The project commenced in 2024, and the products manufactured once it is operational will ensure a supply of materials for local green energy industries such as solar panels, thereby contributing to Oman’s goal of economic diversification under its \"Vision 2040\" and helping to advance green development in the Middle East, North Africa, and beyond. During the project construction, all of the more than 500 pieces of equipment required for installation were placed in place in just one go. Advanced construction techniques such as downward welding of cellulose, along with green building materials, were employed, which significantly reduced construction costs and carbon emissions ； Recently, the project team has also actively organized environmental protection activities, cleaning up 1,000 meters of the Sukhar coastline of marine debris such as plastic bottles and abandoned fishing nets, thereby demonstrating the sense of social responsibility of Chinese enterprises. Next, LiuHuaJian will, in line with the group company’s \"135\" development strategy and the \"123456\" work approach, vigorously promote the \"Six Dedication\" spirit and advance the construction of overseas projects with high quality. By delivering high-standard brand projects, it will contribute to the establishment of the \"three important platforms and one golden brand\" for foreign cooperation, assist Oman in developing new energy industry clusters, and offer China Chemical’s expertise to support the diversified development of the Middle East, North Africa, and other regions.
