Taiwan has agreed to purchase 30% of the natural gas from a proposed pipeline project in Alaska, President Donald Trump announced Tuesday during a rally in the state. The financial terms and other details of the agreement were not immediately available.

The announcement builds on an agreement reached last year between Taiwan's state-owned energy company, CPC Corp., and the Alaska Gasline Development Corp. Under that arrangement, CPC agreed to purchase liquefied natural gas (LNG) and invest in the Alaska pipeline project.

Taiwanese President Lai Ching-te previously described the investment as a way to strengthen the island's energy security. Taiwan relies heavily on imported energy to meet its electricity needs, making stable supplies of natural gas an important consideration for its economy.

The Alaska project is intended to transport natural gas from the state's North Slope to markets, including overseas customers. A major purchase commitment from Taiwan could provide a significant prospective market for the project, although the specific terms of the newly announced arrangement remain unclear.

Further details are needed to determine how the 30% commitment relates to the earlier CPC agreement, including the volume of gas involved, the timeline for deliveries, and the financial obligations of the parties.
