There are several Western powers that travelled to Asia to colonise Asian territories and also to monopolise several trades, such as spices and textiles. Some of the Western powers that came to Asia included the British, the Portuguese, the Spanish, the French, and the Dutch. I think it would be interesting to select one of the Western colonisers and mark out their trade route chronologically, and identify the most famous art pieces that came out of each Asian colony.
For example, if we were to look at the Dutch:
We can track the trade route they took in Asia, perhaps select 4 territories and select the art works that came out from these places.
