Chinese business leaders are in Japan showcasing world-leading sustainable technologies as part of Expo 2025 Osaka, with executives emphasizing the need for private companies to act as "practitioners of green development." On Friday, leaders from China and around the world gathered at the UN Pavilion to share their vision for a sustainable future during a conference hosted by the United Nations Institute for Training and Research (UNITAR). The event focused on advancing the Sustainable Development Goals (SDGs), with executives from China’s construction and oxygen generation industries presenting how they are raising global sustainability standards. UNITAR officials stressed the importance of engaging with these companies in order to drive progress toward the SDGs. "A lot of the private sector is getting more and more important because without their knowledge and power we would not be able to achieve the Sustainable Development Goals. So we work very closely with the private sector," said Chisa Mikami, head of the UNITAR Hiroshima Office. Meanwhile, a parallel conference at the China Pavilion, jointly organized by the China Chamber of International Commerce and the China Council for the Promotion of International Trade, highlighted Chinese companies' best practices in sustainability. "In the global sustainable development process, our company positions itself as a co-builder of global sustainable infrastructure and a responsible development partner. Our role goes beyond that of a traditional engineering contractor; we are also practitioners of green development," said Fang Zheng, General Counsel and CCO of Hunan Construction Investment Group. UNITAR also spotlighted its Asia‑Pacific Youth Ambassador Program, which nurtures young innovators and encourages them to develop creative solutions for the SDGs. "We have already witnessed some of the projects they have proposed. They made it happen in one year or two years. Some of them, after they go to university, they will have much more chance to actually work with a wider range of people," said Junko Shimazu, programme officer of UNITAR Hiroshima Office.
