In the 18th century, Asia was making and distributing goods that were valued by other areas, namely cotton, silk and tea. Europe on the other hand, was not producing products of interest to the other parts of the world. Hence, although Europe was wealthy, this dynamic shows that there may be a reversal of power because it was consistently expanding money, yet hardly bringing in currency. America's crops were not initially appealing to Europeans. Tobacco's demand had to be advertised, and eventually Europe became interested in this particular plant. In time, there was rather regular trade between the Americas and Europe for such crops as tobacco, cotton, and also goods available in South America.
