President Donald Trump on Tuesday touted his administration’s work on a proposed Alaska pipeline, underscoring his push to invigorate a long-stalled $44 billion project to transport natural gas across the state and export it overseas.

Different versions of the Alaska LNG project have been discussed in Alaska for decades, and there are longstanding questions about how it would pencil out.

Alaska political leaders on Wednesday broadly welcomed President Donald Trump’s remarks to Congress talking up the prospects of the state’s long-sought but faltering natural gas pipeline. In his speech to a joint session of Congress on Tuesday night, the president said, “It will be truly spectacular. It’s all set to go.”

Japan, South Korea and other countries want to partner with the United States in a "gigantic" natural gas pipeline in Alaska, U.S. President Donald Trump said on Tuesday, claiming they would invest "trillions of dollars each.

The $44 billion Alaska LNG project, which U.S. President Donald Trump touted Japan, South Korea and other nations “want to invest trillions of dollars each,” involves constructing a 1,300-km pipeline from Alaska’s North Slope to the southern coast.

Some officials in South Korea say agreeing to the pipeline investment might placate the U.S., but Trump is still threatening tariffs.

US President Trump has announced that his administration was "working on a gigantic natural gas pipeline" in Alaska in his first address to both chambers of the US parliament since returning to office in January.

U.S. President Donald Trump said on March 4 that his administration was advancing a major natural gas pipeline project in Alaska, attracting investment interest from Japan, South Korea, and other nations.
