There is at the end of the day, no such thing as global free trade:- because almost all countries and anybody who wishes to sell goods globally, soon finds themselves at war with everyone else, who's also trying to sell the same type of thing. So unless you have a totally unique product, service or good, then welcome to the global trade war, in which everybody is fighting for market share, subsidies and political leverage over one another. It's capitalism at it's worse, healthy competition turns into a global shooting match, with most of the rich nations finding themselves in top spot, to dictate terms and on many levels, to the poor producers of the world.
If the past is anything to go by, then future global trade and technology transfer, especially within a capitalist system, seems assured. It's a scary prospect, as competing nations acquire and learn to use potential technologies capable of being turned into WMD.
