Japan will send a “high-level delegation” to the second Belt and Road Forum in China later this month, Japanese officials agreed during high-level talks between the two countries this weekend.

Japanese officials said they will attend in order to expand their cooperation in Belt and Road-related fields. Minister of Foreign Affairs Wang Yi said the dialogue over the weekend was “constructive,” though China expects Japan to participate in the Belt and Road Initiative with a “more positive and clear” manner.

Japan has not specified who they will send to the forum. Though the U.S. has the Ministry of Foreign Affairs said Friday that White House adviser Matt Pottinger will lead a delegation to the event. Pottinger also led the U.S. delegation to the first Belt and Road Forum, which took place in Beijing in 2017.

During a high-level conference in March, Wang said the Belt and Road Forum will be the “most important” diplomatic event in China this year.
