June 13 (UPI) — South Korea had a trilateral meeting with officials from the United States and Japan in Tokyo on North Korean affairs this week, the foreign ministry said Saturday.

The ministry said the talks took place Friday involving Kim Sang-il, head of the ministry’s North Korean Nuclear Affairs Policy Division; David Wilezol, U.S. deputy assistant secretary of state for Northeast Asia; and Kengo Otsuka, deputy director-general for Asian and Oceanian affairs at the Japanese foreign ministry.

The officials shared their views on recent affairs on the Korean Peninsula and in the rest of Northeast Asia, and also reaffirmed their commitment to denuclearize North Korea and to ensure the implementation of U.N. and autonomous sanctions, Seoul’s foreign ministry said.

“We explained our effort in easing tension and building trust in inter-Korean relations, and also exchanged views on trilateral cooperation in ensuring peace and security on the Korean Peninsula,” the ministry added.

In a press release issued Friday, the Japanese foreign ministry noted the three officials “expressed their serious concerns over North Korea’s nuclear and missile development.” They also agreed to work closely on the advancement of Russia-North Korea military cooperation and North Korea’s malicious cyber activities, Tokyo’s ministry said.

Also in Tokyo on Friday, the three countries held their trilateral secretariat managing board meeting. Wilezol and Otsuka were joined by Yi Won-woo, director-general for North American affairs at the South Korean foreign ministry.

These officials reviewed progress on three-way cooperation on issues such as security, the economy and technology, and discussed specific ways that can produce concrete outcomes, the ministry here said.
