Prime Minister Shinzo Abe and South Korean President Park Geun Hye plan to hold what will be their first official meeting on the sidelines of a trilateral summit with China that Seoul proposes hosting from Oct. 31 to Nov. 1, diplomatic sources said Thursday.

If realized, it would be the first trilateral summit since May 2012. The summit would involve Abe, Park and Chinese Premier Li Keqiang.

Referring to an agreement struck Wednesday between Park and Chinese President Xi Jinping to hold the trilateral summit "at a convenient time including late October or early November," Chief Cabinet Secretary Yoshihide Suga said Abe "would be happy to receive an offer" from South Korea for talks with Park on the fringe of such a gathering.
