Final answer:
Spices, tea, porcelains, silk, and cotton are the goods that made China very wealthy because of the high demand by Europeans.
Step-by-step explanation:
The goods that made China very wealthy due to high demand by Europeans were spices, tea, porcelains, silk, and cotton. Europe, especially countries like Portugal, Spain, and England, established lucrative trade routes with China, importing these goods and ensuring continued access to Asia.
In return, China demanded payment for its exports in silver, resulting in a very favorable balance of trade with Europe.
