International Trade

[kato13]

While re-watching the 1978 History documentary series "Connections" (which I wholeheartedly recommend) I started thinking about the existence of international trade through the ages.

I started thinking what products are so easily produced and produced in such numbers that even the twilight war would not reduce production to a point where trade is not profitable.

Opium from Afghanistan was the first thing I though of. Quinine from Java also would be important as I am assuming malaria rates would be shooting up. Some narcotics and coffee from South America would also see international movement. Spices from Asia as always would be in demand.

I'd like to hear other opinions or other expected trade routes.
