Kim Gunn, Seoul's special representative for Korean Peninsula peace and security affairs, will meet with Sung Kim, Washington's special representative for North Korea, and Takehiro Funakoshi, director general for Asian and Oceanian affairs at Japan’s Foreign Ministry, in Tokyo on Wednesday.

The meeting planned for Wednesday comes on the heels of a trilateral meeting of the security chiefs last week, as the three countries are seen to be ratcheting up efforts to strengthen trilateral cooperation.

According to Seoul’s Foreign Ministry, the envoys of the three countries will exchange their assessment of the security situation on the Korean Peninsula and discuss possible measures for North Korea’s denuclearization.

Announcing Sung Kim’s trip to Tokyo, the US State Department said the three countries are to discuss a broad range of issues, including their joint efforts for “complete denuclearization of the Korean Peninsula,” in a press release Friday.

The US special representative will also stress the US’ commitment to bringing the North to dialogue for denuclearization, while they take all the necessary actions to address the threats posed by Pyongyang, the press release added.

During his three-day stay in Tokyo, Kim Gunn will also discuss the follow-up measures to promote the South Korean government's "audacious initiative" promising economic benefits to the North in return for steps toward denuclearization, Seoul's Foreign Ministry said.

Kim will hold bilateral talks with his US and Japanese counterparts in Tokyo as well, the ministry added.

The nuclear envoys of the three countries previously met in a group meeting in Bali, Indonesia, in July.

Last week, South Korea’s national security adviser Kim Sung-han met with US national security adviser Jake Sullivan and Japan’s national security adviser Takeo Akiba in Honolulu, where they vowed to take stern measures in case the North carries out its seventh nuclear test.

Kim Sung-han said the three countries agreed to “maximize our joint efforts together with international society to make sure the North understands that its seventh nuclear test is a clear mistake.”

The intelligence authorities of Seoul and Washington assess that Pyongyang may conduct a nuclear test this year, as it is seen to have finished the necessary preparations. If the North does push ahead with its nuclear test, it would be its seventh, after the last one in September 2017.

The Korean security adviser also said the reactions of the three countries would “certainly be different from those until now,” if the North carries out the seventh nuclear test.
