I don’t recall exactly the year but there was a commerce problem between Japan and either France or Germany in the 80s. Japan didn’t want European cars in their market so made up a special inspection of engines for foreign cars. So the other side picked the best selling export I think Nagasaki bikes, and made up some special inspection as well. They ended up both allowing the free sale of both vehicles
Someone made a comment awhile back, if international diplomacy was as easy as real estate then we would have had much less wars. It is hard, it requires specific skills, it requires years of trust building and give and take. All these idiots get is short timed wins that end up costing more in the long run.
