Korea reassesses trade, security ties after Democrats sweep US Congress

Seoul is assessing the effects of the Democrats’ sweeping U.S. midterm victory on trade, security and nuclear cooperation while seeking to keep agreements with Washington on track. The government says it does not expect the result to alter the Korea-U.S. alliance, which it says has had bipartisan support for more than 70 years. Officials are reviewing possible policy effects and plan to strengthen outreach to the incoming Congress. Areas under review include nuclear cooperation, wartime operational control and Korea’s investment commitments in the United States.

Presidential chief spokesperson Kang Yu-jung said the government would continue communicating and cooperating with the U.S. administration and Congress.

Prime Minister Han Seong-sook said relevant ministries were reviewing individual policies and pledged more frequent meetings with ministers responsible for diplomacy and security.

The Ministry of Foreign Affairs said it would expand its networks among members of the incoming Congress to support the alliance and maintain continuity in bilateral cooperation.

Potentially affected issues include expanded uranium enrichment and spent nuclear fuel reprocessing rights, nuclear-powered submarines, and the transfer of wartime operational control.

The article says Korea’s $350 billion U.S. investment commitment is unlikely to ease substantially because Democrats also prioritize attracting investment and creating American jobs.

Cheong Wa Dae highlights bipartisan foundation of Seoul-Washington alliance

President Lee Jae Myung and presidential chief of staff Lim Kwang-hyun enter a weekly meeting with senior secretaries at Cheong Wa Dae in Seoul, Thursday.

Seoul is assessing the fallout from the Democrats’ sweeping victory in the U.S. midterm elections, Tuesday, preparing for possible changes in trade, security and nuclear cooperation while seeking to keep existing agreements with Washington on track.

"The government will analyze changes in the U.S. political landscape following the midterm elections and continue to communicate and cooperate closely with the U.S. administration and Congress," presidential chief spokesperson Kang Yu-jung said during a press briefing, Thursday.

She also said the government "does not expect the outcome of any particular election to affect the Korea-U.S. alliance," noting the alliance has developed over more than 70 years with bipartisan support in the U.S.

A separate Cheong Wa Dae official said the presidential office "has been continuously reviewing how to respond to shifts in the balance of power in the U.S. Senate and House."

“Given the complexities of Korea-U.S. relations, Cheong Wa Dae and relevant ministries are closely monitoring developments,” the official said.

Presidential chief of staff Lim Kwang-hyun reportedly instructed senior staff to develop responses to the election outcome’s potential effects on U.S. tariff policy and bilateral security cooperation.

The Democratic takeover of both the Senate and the House means Seoul must maintain cooperation with U.S. President Donald Trump and the White House while strengthening ties on Capitol Hill, where lawmakers could play a greater role in scrutinizing or shaping agreements involving trade, nuclear cooperation and defense.

Prime Minister Han Seong-sook also noted Thursday that bipartisan support for the alliance would help prevent major changes in ties.

“Both Democrats and Republicans have attached importance to the alliance between our two countries, so I do not expect any very significant changes in relations with Korea,” she told the National Assembly’s Special Committee on Budget and Accounts.

Han nevertheless acknowledged that “the Democrats’ victory was much stronger than expected” and called for closer examination of individual policies.

“There are issues that require more detailed analysis and further responses,” she said, adding that relevant ministries were conducting reviews.

She also pledged more frequent meetings with ministers handling diplomacy and security to coordinate responses.

Meanwhile, the Ministry of Foreign Affairs said it is preparing to strengthen outreach to members of the incoming Congress, building on contacts with key lawmakers and candidates during the campaign.

“We will strengthen communication with key figures elected to Congress and expand our networks in support of the Korea-U.S. alliance,” it said.

The ministry added that Seoul would reinforce communication channels to ensure continuity in bilateral cooperation.

Potentially affected policies include expanded uranium enrichment and spent nuclear fuel reprocessing rights, nuclear-powered submarines, the transfer of wartime operational control (OPCON) and Korea's $350 billion investment in the U.S.

Nuclear cooperation could require particularly close congressional engagement, as revising the bilateral agreement and advancing arrangements for nuclear-powered submarines could face legislative support alongside negotiations with the administration.

OPCON transfer and defense spending commitments will remain subjects of bilateral security consultations.

Seoul will need to assess whether the congressional shift affects Washington’s approach to implementing those agreements.

Investment pressure, however, is unlikely to ease substantially, as Democrats also prioritize attracting investment and creating American jobs, limiting prospects for a significant reduction in Korea’s commitments.

青瓦台强调首尔-华盛顿联盟的两党基础

周二，首尔正在评估民主党在美国中期选举中取得压倒性胜利的影响，为贸易、安全和核能合作方面可能出现的变化做准备，同时寻求保持与华盛顿的现有协议继续有效。

总统首席发言人康裕贞周四在新闻发布会上表示：“政府将分析中期选举后美国政治格局的变化，并继续与美国政府和国会密切沟通与合作。”

她还表示，政府“不认为任何特定选举的结果会影响韩美同盟”，并指出该同盟是在美国两党支持下发展起来的，已有70多年的历史。

另一位青瓦台官员表示，总统府“一直在不断研究如何应对美国参众两院权力平衡的变化”。

“鉴于韩美关系的复杂性，青瓦台和相关部门正在密切关注事态发展，”该官员表示。

据报道，总统幕僚长林光铉指示高级幕僚制定应对选举结果可能对美国关税政策和双边安全合作产生的影响的措施。

民主党掌控参众两院意味着首尔必须与美国总统唐纳德·特朗普和白宫保持合作，同时加强与国会山的联系，因为国会议员可以在审查或制定涉及贸易、核合作和国防的协议方面发挥更大的作用。

韩国总理韩成淑周四也指出，两党对联盟的支持将有助于防止两国关系发生重大变化。

“民主党和共和党都非常重视我们两国之间的联盟，所以我预计与韩国的关系不会发生任何重大变化，”她对国会预算和账目特别委员会表示。

尽管如此，韩承认“民主党的胜利远超预期”，并呼吁对各项具体政策进行更深入的研究。

她表示：“有些问题需要更详细的分析和进一步的回应”，并补充说，相关部门正在进行审查。

她还承诺将更频繁地与负责外交和安全的部长们举行会议，以协调应对措施。

与此同时，外交部表示，正准备加强与即将上任的国会议员的沟通，并在竞选期间与主要议员和候选人建立联系的基础上。

声明称：“我们将加强与国会重要人物的沟通，并扩大我们的网络，以支持韩美同盟。”

该部还表示，首尔将加强沟通渠道，以确保双边合作的持续性。

可能受影响的政策包括扩大铀浓缩和乏核燃料后处理权、核动力潜艇、战时作战指挥权（OPCON）的移交以及韩国对美3500亿美元的投资。

核能合作可能需要国会的密切参与，因为修订双边协议和推进核动力潜艇的安排可能需要在与政府谈判的同时获得立法支持。

作战指挥权移交和国防开支承诺仍将是双边安全磋商的主题。

首尔需要评估国会的这一转变是否会影响华盛顿执行这些协议的方式。

然而，投资压力不太可能大幅缓解，因为民主党人也优先考虑吸引投资和创造美国就业机会，这限制了韩国大幅减少投资承诺的可能性。
