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.

Investors have balked at the project, stalling its progress. But under the threat of tariffs, Japan and South Korea have started exploring ways to invest in Alaska L.N.G.

China’s foreign ministry spokesman, Lin Jian, warns that China would fight ‘to the bitter end’ in ‘a tariff war, a trade war, or any other kind of war.’

South Korea's energy minister said a massive gas pipeline could help diversify the sources of natural gas and that the country would hold talks with the US to move the project forward.

U.S. President Donald Trump has criticized South Korea for imposing more unfair tariffs on American products than China. The President also criticized the country for issuing subsidies to foreign chipmakers like Samsung Electronics Co.
