Former President Donald Trump recently urged South Korea to finalize its participation in a $50 billion Alaska liquefied natural gas (LNG) project or face increased costs, hinting at potentially doubling tariffs or charges if Seoul does not sign on soon. During remarks to reporters, Trump emphasized that he had not “jumped the gun” by announcing South Korea’s involvement, despite the country indicating it was still evaluating the deal. He did not clarify what costs would be doubled but implied a financial penalty for delay or refusal.

South Korean officials have confirmed that their commitment to the Alaska LNG project remains contingent on a thorough assessment of its commercial viability and compliance with domestic regulations. They have yet to finalize decisions regarding investment and involvement, contributing to a disconnect between Washington's announcements and Seoul’s official position. South Korean media speculated that Trump’s threat could refer to tariff increases, but no formal confirmation has emerged.

In addition to the LNG project, Trump announced an $8.4 billion investment in an enhanced oil recovery initiative, which uses advanced methods like carbon dioxide injection to extract more crude oil from existing fields. However, South Korean industry ministry sources stated the oil recovery deal was not part of the formal agreements between the two countries and that Seoul was seeking clarification through official trade channels regarding this announcement.

The tension between the two governments highlights ongoing challenges in negotiating international infrastructure and energy partnerships. While the United States is keen to secure South Korean investment in key projects like Alaska LNG, Seoul remains cautious, prioritizing commercial and regulatory scrutiny before committing. The situation underscores the complexities of cross-border investment deals, especially amid evolving political and economic considerations.
