The foreign ministers of Japan, China and South Korea have agreed to promote cooperation for other countries in Asia in such areas as environmental conservation and disaster risk reduction.
Taro Kono of Japan, Wang Yi of China and Kang Kyung-wha of South Korea drew up a paper on "Trilateral+X" cooperation at their meeting in Beijing on Wednesday.
The paper expresses the countries' willingness to jointly help promote sustainable common development in Asia and beyond.
It says that "given the large number of developing countries in Asia and the acute problem of uneven and inadequate development Asia faces, it is imperative to explore new areas and models to improve trilateral cooperation."
The paper cites sustainable economies, ecological and environmental conservation, and disaster risk reduction as major areas of cooperation. Health, poverty alleviation and people-to-people exchanges are also on the list.
The three countries plan to explore specific models and projects for cooperation that will be voluntary, equal-footed, open, transparent and achieve win-win outcomes.
