Joining for part of the U.S. officials’ trip were representatives from Asian countries, including Japan, South Korea, the Philippines, Taiwan and United Arab Emirates. Asian countries are being courted to sign onto the Alaska gas project, which has floundered for years to gain traction amid cost and other concerns. The project, as proposed, would include a nearly 810-mile (1,300-kilometer) pipeline that would funnel gas from the North Slope to port, with an eye largely on exports of liquefied natural gas.
