Representatives of 18 countries agreed Saturday to enhance cooperation between their public and private sectors to expand useful environmental technologies to achieve both economic growth and greenhouse gas reductions.

The agreement came at the East Asia Low Carbon Growth Partnership Dialogue held in Tokyo.

At the meeting, Japan announced its plan to comprehensively support the construction of urban infrastructure in developing countries employing advanced technologies, such as energy-efficient public transport systems and dispersed power systems utilizing renewable energy.

"The conference was meaningful in promoting tangible countermeasures against global warming by enhancing regional cooperation in East Asia, the largest greenhouse gas emission district in the world," said Foreign Minister Fumio Kishida after concluding the meeting.

Tokyo took the initiative in holding the meeting, which was attended by China, India and ASEAN member countries as well as Russia and the United States. It was the second such conference following one in April last year.

The amount of greenhouse gases emitted by the 18 attending countries accounts for about 60 percent of the global discharge.
