Experts see no quick fix to Korea-US intelligence rift

South Korea and the United States have maintained restrictions on some North Korea-related intelligence sharing for six months, with experts saying Washington’s mistrust makes a quick resolution unlikely. Nam Sung-wook attributed the dispute to distrust of Unification Minister Chung Dong-young and NIS chief Lee Jong-seok, while Jun Bong-geun described it as a structural shift in the alliance. The NIS said cooperation remains broad, and Gen. Jin Yong-sung said military readiness has not been affected.

The NIS said intelligence cooperation continues on North Korean missiles, conventional military capabilities, developments in North Korea, international relations, cybersecurity and counterintelligence.

Questions over intelligence cooperation intensified in March after Chung Dong-young publicly identified North Korea’s Kusong region as a location housing a uranium enrichment facility.

Nam Sung-wook said replacing Chung Dong-young and Lee Jong-seok could ease tensions, but President Lee Jae Myung is unlikely to take that step.

Jun Bong-geun said the alliance is shifting from a traditionally hierarchical relationship toward a mutually beneficial strategic partnership and called for a unified national consensus on strategic priorities.

Spy agency claims cooperation remains broad despite acknowledged restrictions

Although the South Korean government insists its alliance with the United States remains strong despite six months of restrictions on North Korea-related intelligence sharing, experts see little prospect of a quick resolution, warning that Washington’s mistrust runs deep and the dispute reflects broader structural strains in the alliance.

Nam Sung-wook, a chair professor at Sookmyung Women’s University, said the restrictions reflect deep-seated U.S. mistrust of specific figures in the Lee Jae Myung administration and warned the situation was unlikely to improve soon.

“The U.S. is showing a deep-seated distrust toward key figures such as Unification Minister Chung Dong-young and National Intelligence Service (NIS) chief Lee Jong-seok in the Lee Jae Myung administration and claiming that they cannot have high-level intelligence-sharing meetings. It is worrisome as it is also fundamentally hurting the allies,” he said.

He said Seoul has strong reasons to resolve the restrictions quickly but warned that Washington’s concerns may be difficult to overcome in the near term.

“It will not be beneficial for South Korea to let the situation continue and the restriction on intelligence sharing should be resolved as early as possible. But given the severity of Washington's skepticism, it may not be settled soon.”

He added that replacing the officials at the center of Washington’s concerns — Unification Minister Chung and NIS chief Lee — could help ease tensions, but said President Lee is unlikely to take such a step.

The dispute returned to the spotlight Sunday after the NIS dismissed a local news report claiming Washington had narrowed its intelligence sharing with Seoul to missile-related information only.

"We make it clear once again that, aside from some information that led to the intelligence-sharing restrictions already acknowledged by our government, South Korea and the U.S. are actively cooperating across a wide range of areas, including Pyongyang's missiles, conventional military capabilities and what is happening in North Korea, as well as international relations, cybersecurity and counterintelligence," the NIS said in a press release.

Questions over bilateral intelligence cooperation have persisted since March, when Chung publicly disclosed that North Korea’s Kusong region was among the locations housing a uranium enrichment facility. The disclosure reportedly prompted Washington to restrict the sharing of some North Korea-related intelligence with Seoul.

Joint Chiefs of Staff Chairman Gen. Jin Yong-sung acknowledged during a parliamentary hearing Thursday that some defense intelligence sharing has been restricted, while stressing that the limitations have not affected South Korea’s military readiness.

While Nam focused on Washington’s mistrust of specific officials, Jun Bong-geun, a professor emeritus at the Korea National Diplomatic Academy, offered a broader interpretation, arguing that the friction reflects a structural shift as the alliance moves from a traditionally hierarchical relationship toward a more horizontal partnership.

“With the narrative surrounding South Korea-U.S. relations being weaponized for domestic political gains in both Seoul and Washington, it is necessary to take a sober approach. The conflicts need to be decoupled and resolved individually,” he said.

"As the South Korea-U.S. alliance shifts from a traditional hierarchical structure toward a mutually beneficial strategic partnership, friction has emerged as Washington adjusts to this new paradigm," Jun said. "The growing friction cannot be brushed aside as a minor dispute. The two countries must reexamine their approach to the partnership and Seoul must establish a unified national consensus on its strategic priorities."

Jun called for sustained bilateral discussions on how the alliance should operate as the relationship becomes more reciprocal, warning that unresolved differences could continue to surface across security and diplomatic issues.

韩国和美国已对部分涉朝情报共享实施限制长达六个月，专家表示，华盛顿的不信任使得迅速解决问题的可能性不大。南成旭将争端归咎于统一部长官郑东荣和国家情报院院长李钟硕之间的不信任，而全奉根则将其描述为联盟内部的结构性转变。国家情报院表示合作范围依然广泛，金勇成将军也表示军事战备未受影响。

美国国家情报院表示，双方在朝鲜导弹、常规军事能力、朝鲜局势发展、国际关系、网络安全和反间谍等领域继续开展情报合作。

今年3月，郑东荣公开指出朝鲜龟城地区是铀浓缩设施所在地，这加剧了有关情报合作的问题。

南成旭表示，撤换郑东荣和李钟硕可能会缓解紧张局势，但李在明总统不太可能采取这一步骤。

全奉根表示，该联盟正在从传统的等级关系转向互利共赢的战略伙伴关系，并呼吁就战略重点达成全国共识。

尽管存在公认的限制，但间谍机构声称合作范围仍然很广。

尽管韩国政府坚称，尽管过去六个月来与朝鲜有关的情报共享受到限制，但其与美国的联盟依然牢固，但专家们认为迅速解决的可能性不大，并警告说，华盛顿的不信任根深蒂固，这场争端反映了联盟内部更广泛的结构性紧张局势。

淑明女子大学教授南成旭表示，这些限制反映了美国对李在明政府中某些人物根深蒂固的不信任，并警告说这种情况不太可能很快得到改善。

他说：“美国对李在明政府的关键人物，例如统一部长官郑东荣和国家情报院院长李钟硕，表现出根深蒂固的不信任，并声称他们无法举行高级别情报共享会议。这令人担忧，因为它从根本上损害了盟友关系。”

他表示，首尔有充分的理由尽快解除这些限制，但他警告说，华盛顿方面的担忧可能在短期内难以克服。

“让这种情况继续下去对韩国不利，情报共享限制应该尽快解除。但鉴于华盛顿的怀疑态度如此强烈，这个问题可能不会很快得到解决。”

他还补充说，更换华盛顿方面最为关注的官员——统一部长官郑义宣和国家情报院院长李健熙——或许有助于缓解紧张局势，但他表示，李健熙总统不太可能采取这样的措施。

周日，韩国国家情报院驳斥了当地一家新闻媒体的报道，该报道称华盛顿已将与首尔的情报共享范围缩小到仅限于导弹相关信息，此后这场争端再次成为焦点。

“我们再次明确表示，除了一些导致我国政府已经承认的情报共享限制的信息外，韩国和美国正在广泛领域积极合作，包括平壤的导弹、常规军事能力和朝鲜局势，以及国际关系、网络安全和反间谍等领域，”韩国国家情报院在一份新闻稿中表示。

自今年3月郑义宣公开披露朝鲜龟城地区是铀浓缩设施所在地之一以来，双边情报合作问题一直备受质疑。据报道，这一披露促使华盛顿限制了与首尔分享部分涉朝情报。

韩国联合参谋本部议长晋勇成周四在国会听证会上承认，一些国防情报共享受到限制，但他强调，这些限制并未影响韩国的军事战备。

南先生关注的是华盛顿对特定官员的不信任，而韩国国立外交学院名誉教授全奉根则提出了更广泛的解释，认为这种摩擦反映了联盟从传统的等级关系向更加扁平化的伙伴关系转变的结构性变化。

他说：“鉴于围绕韩美关系的论述已被首尔和华盛顿两国用于谋取国内政治利益，因此必须采取冷静的态度。这些冲突需要脱钩，并分别解决。”

“随着韩美同盟从传统的等级结构向互利共赢的战略伙伴关系转变，华盛顿在适应这一新模式的过程中出现了摩擦，”全俊表示。“日益加剧的摩擦不能被视为小问题而置之不理。两国必须重新审视各自的伙伴关系方式，首尔必须就其战略重点达成统一的全国共识。”

俊呼吁就联盟应如何运作进行持续的双边讨论，因为随着双方关系变得更加互惠，他警告说，在安全和外交问题上，未解决的分歧可能会继续浮出水面。
