Officials and business representatives from China and Japan vowed to enhance cooperation in environmental protection and green technology during a high-level seminar conducted by videoconference on Thursday.

Some 300 people attended the China-Japan Green Technology Seminar, which convened at three venues — in Beijing, Tokyo and Qingdao, Shandong province.

The event was organized by the National Development and Reform Commission; Japan's Ministry of Economy, Trade and Industry; the Japan-China Economic Association; and the municipal government of Qingdao.

Eighteen business representatives from both countries shared their views on policies, development models and technology as they relate to such things as energy consumption and recycling.

The Qingdao International Economic Cooperation Zone, one of the seminar's venues, is home to the Qingdao China-Japan Cooperation Hub, which was unveiled in May as a platform specially designed to facilitate projects involving Japanese enterprises and business associations entering the Chinese market. It also covers Chinese investment in Japan.
