U.S. President Donald Trump announced that Taiwan has agreed to purchase 30% of the gas from the Alaska liquefied natural gas (LNG) project for the next 20 years, describing the agreement as a guarantee of the project's success. The Alaska LNG project, valued at $50 billion, is expected to deliver its first gas by 2029, and this deal highlights Taiwan’s commitment to securing energy supplies amid rising demand. Taiwan’s state-owned CPC Corp had reportedly reached an agreement in 2025 to buy LNG and invest in the project, but specific details of the recent arrangement remain unclear.

The announcement comes amid ongoing uncertainty about South Korea’s involvement in the Alaska LNG project. Although President Trump has repeatedly claimed that Seoul committed to joining the venture, South Korea has not confirmed its participation. Trump emphasized that South Korea has already committed $50 billion to Alaska and plans to invest an additional $4.4 billion, even as he threatens increased charges if Seoul delays signing on. These tensions have led to speculation about possible tariffs or penalties that could impact South Korea.

Taiwan’s energy needs have grown substantially, driven in part by the expansion of its semiconductor industry, especially AI-related sectors. The island imports over 90% of its energy and has projected an average annual growth rate in electricity demand of about 2.5% through 2035, second only to a historical peak. This energy demand growth underscores the importance of securing reliable LNG supplies from projects like Alaska LNG, particularly as Taiwan awaits further U.S. defense support amid heightened regional tensions with China.

The Alaska LNG project developer, Glenfarne, aims to bring the pipeline online by 2029, making it a critical future energy source for partners like Taiwan and potentially South Korea. With Taiwan’s recent commitment and ongoing negotiations with other East Asian countries, the project represents a significant strategic energy investment in the region. The White House, Taiwan’s energy ministry, and CPC Corp have yet to comment officially following President Trump’s announcement.
