On Monday morning, he is scheduled to attend the ASEAN Plus Three summit, which will likely be joined by Japanese Prime Minister Shinzo Abe and Chinese Prime Minister Li Keqiang. 

Moon plans to present a vision for closer regional cooperation in efforts to create a "sustainable community" and to express Seoul's commitment to related contributions, Cheong Wa Dae said.

He will then be present at "special lunch on sustainable development" along with the leaders of the other participating nations, as well as UN Secretary-General Antonio Guterres and Kristalina Georgieva, managing director of the International Monetary Fund.

Moon will demonstrate Seoul's determination, as a responsible middle-power nation, to continue backing the global campaign to achieve the sustainable development goals.

In the afternoon, the East Asia Summit will take place with the participation of all the ASEAN members, South Korea, Japan, China, the United States and Russia.

Moon is planning to introduce his government's position on the Korean Peninsula issue and other regional and global affairs.

Moon is expected to encounter Abe during the meetings.

But chances are slim that they will have formal one-on-one talks, Moon's aides said, amid a drawn-out standoff between the neighboring countries. (Yonhap)
