Trump Says Taiwan Agrees to Buy 30% of Alaska LNG Output for 20 Years

President Donald Trump said Tuesday that Taiwan had committed to purchasing 30% of the natural gas produced by the proposed Alaska LNG project for two decades. Speaking at a rally in Alaska, Trump described the agreement as a major step toward ensuring the project's success. However, the financial value and detailed terms of the arrangement were not immediately disclosed.

The announcement follows earlier negotiations between Taiwan and Alaska's energy developers. In 2025, Taiwan's state-owned CPC Corporation reportedly reached an agreement with Alaska Gasline Development Corporation concerning potential LNG purchases and investment in the pipeline. Neither Taiwan's energy ministry nor CPC immediately confirmed Trump's latest announcement, leaving questions about the status of the proposed commitment.

The Alaska LNG project aims to transport natural gas from Alaska's North Slope to export facilities serving international markets. The development is estimated to cost approximately $50 billion and is being advanced by Glenfarne. According to a report submitted to the U.S. government, the company is targeting its first gas deliveries in 2029.

Taiwan's interest in securing additional LNG supplies reflects growing pressure on its energy system. The island imports more than 90% of its energy and is experiencing rising electricity demand associated with AI infrastructure and advanced semiconductor manufacturing. Taiwan's economic affairs ministry expects electricity demand to grow by approximately 2.5% annually through 2035, exceeding projected growth rates in Japan and South Korea.

Washington is also seeking South Korean investment in the Alaska LNG development. Trump has repeatedly stated that South Korea committed $50 billion to the project and recently referred to an additional $4.4 billion investment from the United States. However, Seoul has maintained that its participation remains under discussion and that no final commitment has been reached.

Trump has increased pressure on South Korea to formalize its involvement, warning that delays could result in higher charges. His remarks prompted speculation that the administration might consider additional tariffs, although Trump did not specify which charges could increase. The uncertainty illustrates the challenges of securing financing and international commitments for a large-scale energy infrastructure project.

For Taiwan, a long-term LNG arrangement could help diversify energy supplies and support growing electricity requirements from its technology sector. For the United States, securing substantial purchase commitments from Asian economies could improve the project's commercial viability and strengthen its position as an LNG exporter. Nevertheless, financing, construction timelines and binding agreements remain important considerations.

The proposed Taiwan agreement represents a potentially significant milestone for Alaska LNG, but several uncertainties remain. Confirmation from Taiwanese authorities, clarity on South Korea's participation and progress toward the planned 2029 startup will be critical to determining the project's outlook. Until these details are finalized, the commercial implications of Trump's announcement remain difficult to assess.
