S. Korea, U.S., Japan to Operate System for Sharing Real-Time N.K. Missile Warning Data 'Within this Year': Seoul's Defense Chief

SINGAPORE --- South Korea, the United States and Japan agreed Saturday to operate a system to share North Korean missile warning data in real time "within this year," Seoul's defense chief said, in another move to beef up trilateral cooperation against Pyongyang's growing military threats.

Defense Minister Lee Jong-sup made the remarks after he met trilaterally with his U.S. and Japanese counterparts, Lloyd Austin and Yasukazu Hamada, respectively, on the margins of the Shangri-La Dialogue in Singapore, amid renewed tensions over the North's botched yet defiant launch of a purported space rocket earlier this week.

"While actively implementing the agreed-upon measures between the leaders of South Korea, the United States and Japan, the three countries agreed to elevate security cooperation to another level," he told reporters, referring to the agreement from a trilateral summit in Cambodia last November.

"Especially regarding the real-time sharing of North Korean missile warning data, we decided to connect the respective information sharing systems -- one run between South Korea and the United States and the other between Japan and the United States -- and operate the combined one within this year," he added.

For this, the three countries will hold working-level talks at an early date, he said.

The warning data includes a missile's launch point, flight trajectory and expected point of impact, a Seoul official told reporters, requesting anonymity.

The U.S. Indo-Pacific Command is expected to serve as an intermediary to enable the three-way sharing of the data, he said.

The three countries have been working on the data sharing method in line with an agreement that President Yoon Suk Yeol and his U.S. and Japanese counterparts, Joe Biden and Fumio Kishida, respectively, reached during their summit in Cambodia last November.

Seoul's defense ministry said Saturday's agreement was reached in an effort to enhance each country's ability to detect and assess North Korean missiles.

"The three ministers discussed progress under way through working-level talks on technical issues, and affirmed that this is an important procedure for deterrence, peace and stability on the Korean Peninsula and the region," it said in a statement.

Currently, the real-time sharing of missile warning data is occurring between the South Korean military and the U.S. Forces Korea, and between the Japan Self-Defense Force and the U.S. Forces Japan, while South Korea and Japan do not have a similar direct mechanism, given that they are not treaty allies.

In line with last year's summit agreement, the three countries have been working on procedures for a real-time data-sharing method among the three nations based on a trilateral information sharing arrangement signed in 2014.

In their talks, Lee, Austin and Hamada "strongly condemned" the North's launch this week, which they described as a "long-range ballistic missile," the ministry said.

"(They) strongly condemned North Korea's recent long-range ballistic missile launch -- under the guise of a so-called satellite -- as a grave violation of U.N. Security Council resolutions that ban any launches using ballistic missile technology," it said. "With the enhancing of trilateral cooperation, they agreed to sternly respond in cooperation with the international community."

They also urged the North to immediately stop "reckless" acts that create "tensions" on the Korean Peninsula and comply with the resolutions.

The trio agreed to regularly hold defensive exercises, such as anti-submarine and maritime missile defense exercises, and reaffirmed an agreement to swiftly resume maritime interdiction and anti-piracy exercises as agreed during working-level talks in April, it said.

The three sides plan to create an annual plan on such drills so that they are "predictable" and can be operated "efficiently," the official said.

The ministers expressed "strong opposition" to unilateral action that creates tension in the region and changes to the status quo through "force or coercion," saying they stand together with Ukraine in the ongoing war against Russian invaders, while stressing the importance of "peace and stability" across the Taiwan Strait.

Trilateral cooperation has gained traction in the wake of Pyongyang's saber-rattling earlier this year, including the firing of a purported solid-fuel intercontinental ballistic missile in April. Last year, the regime fired an unprecedented number of missiles.

United States-Japan-Republic of Korea Trilateral Ministerial Meeting (TMM) Joint Press Statement

U.S. Secretary of Defense Lloyd J. Austin III, Japanese Minister of Defense Hamada Yasukazu, and Republic of Korea (ROK) Minister of National Defense Lee Jong-Sup convened a Trilateral Ministerial Meeting in Singapore, June 3, 2023. During the meeting, the three leaders discussed the growing nuclear and missile threats from the Democratic People’s Republic of Korea (DPRK) as well as efforts to enhance trilateral security exercises and address common security challenges in the Indo-Pacific region.

The Secretary and the two Ministers pledged that the United States, Japan, and the ROK will cooperate closely toward their shared commitment to achieve the complete denuclearization of the Korean Peninsula in accordance with United Nations Security Council resolutions (UNSCRs). They shared their deep concerns about, and condemnation of, the DPRK’s weapons of mass destruction and ballistic missile programs, which pose a grave threat to international peace and stability, and they committed to address these concerns through concerted trilateral cooperation. In particular, the Secretary and the two Ministers condemned DPRK’s recent claimed space launch using ballistic missile technology as it constitutes a serious violation of relevant UNSCRs. They also renewed their determination to respond firmly to the DPRK threat through increased trilateral cooperation as well as cooperation with the international community. Additionally, they called for full implementation by the international community of relevant UNSCRs. They underscored the importance of sustained international efforts to deter, disrupt, and ultimately eliminate the DPRK’s illicit ship-to-ship transfers. They urged the DPRK to immediately cease its irresponsible actions that create tension on the Korean peninsula and in the region, and to abide by its obligations under all relevant UNSCRs.

In line with the commitments made by U.S. President Biden, Japanese Prime Minister Kishida, and ROK President Yoon at the Phnom Penh Summit on November 13, 2022, the Secretary and the two Ministers recognized trilateral efforts to activate a data sharing mechanism to exchange real-time missile warning data before the end of the year in order to improve each country’s ability to detect and assess missiles launched by DPRK.

The Secretary and the two Ministers discussed the ongoing progress being made through technical working-level consultations and noted that this is a major step for deterrence, peace and stability. They also pledged to make further progress toward operationalizing the trilateral mechanism initially over the next few months.

The Secretary and the two Ministers further affirmed the three sides will utilize the 2014 U.S.-Japan-ROK Trilateral Information Sharing Arrangement to facilitate coordination and cooperation among all three sides. They also welcomed the recent normalization of the bilateral General Security of Military Information Agreement between Japan and the ROK. In addition, they concurred on the need to contribute to defense-related confidence building measures among the countries in the region and committed to strengthening cooperation to institutionalize such efforts.

The Secretary and the two Ministers discussed other regional security issues as well as DPRK threats and all reiterated the importance of deepening trilateral cooperation on key issues to promote a free and open Indo-Pacific, including information sharing, high-level policy consultations, and trilateral exercises. They further discussed steps to follow up on these issues.

Additionally, the Secretary and the two Ministers affirmed their commitment to swiftly conduct maritime interdiction exercises and anti-piracy exercises, and they pledged to further identify other areas, including disaster relief and humanitarian assistance, where the three countries intend to expand trilateral cooperation. They committed to regularizing defensive exercises that contribute to strengthening trilateral responses to the DPRK's nuclear and missile threats and deterring against those threats, including anti-submarine exercises and missile defense exercises.

The Secretary and the two Ministers stressed the importance of the rule of law and expressed strong opposition to any unilateral actions that seek to alter the status quo by force or coercion and increase tensions in the region. They reaffirmed their commitment to stand with Ukraine against Russia’s unprovoked and brutal war of aggression and to recognize that Russia’s actions are a serious violation of territorial integrity and sovereignty which undermines the fabric of the entire international order. They emphasized the importance of peace and stability across the Taiwan Strait. They shared concerns on activities that are inconsistent with international law, in particular the United Nations Convention on the Law of the Sea and stressed the importance of fully respecting international law, including freedom of navigation and overflight and other lawful uses of the sea.

The United States reaffirmed its steadfast alliance commitments to Japan and the ROK backed by the full range of U.S. capabilities, including nuclear. Japan and the ROK highlighted the importance of their bilateral ties and trilateral cooperation to protect and advance their shared security goals. The Secretary and the two Ministers committed to work closely together for peace and stability in the region and around the world.
