U.S. and Japan Reach Trade Deal
Japan has had high tariffs on US products for decades.
As to the LNG pipeline deal, it is possible. Even probable that some form of this takes place. The nature and shape of that deal is not, in fact, done. Japan and the US are not the only players in this deal. South Korea is also a major player. Other countries may want in on it as well. If done at scale this is a project that could actually work.
