Vientiane: The ceremony in Vientiane was attended by more than 100 representatives from government and business sectors of both Laos and China. Prime Minister Sonexay Siphandone presided over the event, pressing the start button to officially launch the project.
According to Lao News Agency, Mr Meng Zhenping, Chairman of China Southern Power Grid Co., Ltd.

It is expected to supply around 3 billion kilowatt-hours of clean electricity annually, significantly contributing to greener and low-carbon energy development while bringing tangible benefits to people in both countries.
Minister of Industry and Commerce Mr Malaythong Kommasith described the project as a strategic backbone for Laos’ power sector. He emphasized that it will help mitigate domestic transmission bottlenecks and bolster the expansion of renewable energy, especially in northern Laos.
Chinese Ambassador to Laos, Ms. Fang Hong, remarked that the project serves as a ‘green energy artery’ enhancing bilateral connectivity. She affirmed that China is prepared to employ such initiatives as a model to deepen cooperation in clean energy, support Laos’ energy transition, and further the building of a closer China-Laos community with a shared future.
