Michigan Republican Rep. John Moolenaar, chairman of the House Select Committee on China, sent a five‑page letter to Secretary of State Marco Rubio warning that the Republic of Korea’s (ROK) recent shift toward the People’s Republic of China (PRC) poses “significant risks for the United States.” The letter, released Monday, comes as President Trump announced on social media that he met South Korean President Lee Jae‑Myung in New York and secured a $200 billion commitment for new U.S. investments.
Why the shift matters
Moolenaar noted that since President Lee took office in June 2025, Seoul has deepened economic, technological, and diplomatic ties with Beijing. He cited nine months of high‑level leader engagement, expanded semiconductor joint ventures, and a series of fourteen memoranda of understanding covering trade, science, digital links, intellectual‑property cooperation, and quarantine standards.
According to the chairman, these moves create “parallel export‑control channels” that could undermine allied coordination and give the Chinese Communist Party leverage over global supply chains. He pointed to Samsung Semiconductor’s memory plants in Xi’an and Dalian and SK Hynix’s chip fab in Wuxi as concrete examples of Chinese‑linked leverage points.
Security concerns for the United States
The letter quoted Rubio’s recent House testimony, in which he warned that South Korean leaders are “taking positions that run contrary to the national interests of the United States.” Moolenaar argued that the ROK’s alignment threatens the 2026 National Defense Strategy’s assessment that Seoul can assume primary responsibility for deterring North Korea while also supporting broader regional contingencies.
He also highlighted a pattern of biased enforcement of South Korean law that favors Chinese firms over U.S. companies. Chinese e‑commerce platforms, including an Alibaba subsidiary, serve 16.5 million South Korean users each month and have been designated a Chinese military company by the Pentagon. By contrast, American firm Coupang has faced “large‑scale legal harassment,” including more than 400 facility raids and $409 million in penalties.
Congressional response
The House Armed Services Committee’s FY 2027 defense authorization bill now requires the Pentagon to conduct an assessment of Chinese Communist Party malign influence in South Korea and the associated risks to U.S. defense interests. Moolenaar urged the State Department to brief Congress by Oct. 31 on Seoul‑Beijing ties and the administration’s response.
He also criticized a March leak of classified U.S. intelligence by South Korean Unification Minister Chung Dong‑young, which led to restrictions on intelligence sharing with Seoul.
President Trump’s diplomatic outreach
President Trump’s meeting with President Lee underscores a bipartisan commitment to reinforcing the U.S.–ROK alliance. The $200 billion investment pledge signals confidence that American capital can still thrive alongside South Korean partners, even as Beijing seeks greater influence.
“Our alliance with Seoul remains critical,” Moolenaar wrote. “A structural shift toward Beijing requires close monitoring and decisive action to protect American security and economic interests.”
What’s next?
The State Department has declined to comment, and the South Korean embassy has not responded to requests for comment. As the Trump administration continues to prioritize a strong, values‑based foreign policy, congressional leaders say they will keep a vigilant eye on any developments that could jeopardize the United States’ strategic position in East Asia.
