South Korean gas pipeline and steel pipe stocks surged on September 3 after U.S. President Donald Trump reiterated that South Korea and Japan would participate in the Alaska liquefied natural gas project. Shinsung Steel hit the daily price limit at ₩2,105, up 29.86%, while Kumkang Steel rose about 21% and TCC Steel gained 15–18%. Trump said Japan and South Korea would go to Alaska to load fuel and oil, build pipelines and handle related work. The proposed project would move North Slope gas through a pipeline of about 1,300 kilometers to Nikiski near Anchorage for liquefaction and shipment to Asian markets. Investors have interpreted Trump's repeated remarks as a potential source of future orders for South Korean steel and pipe makers, although neither South Korea nor Japan has officially confirmed investment and no contracts or orders have been announced.
