Japan will host a trilateral summit with China and South Korea on Wednesday, to be held after a two-and-a-half year hiatus, with the leaders expected to focus on the denuclearization of North Korea.

The gathering will bring together Prime Minister Shinzo Abe, Chinese Premier Li Keqiang and South Korean President Moon Jae-in to talk about how to strengthen their cooperation in prodding Pyongyang to abandon its nuclear and missile programs, Japanese officials said.

The trilateral summit — the seventh of its kind — will follow the landmark meeting between Moon and North Korean leader Kim Jong Un late last month and come ahead of the first-ever U.S.-North Korean summit between President Donald Trump and Kim expected in the coming weeks.
