What two countries lead the world in production of tea in1773?

It's impossible to say for certain which two countries led the world in tea production in 1773. Here's why:

* Limited Data: Accurate global tea production data for that period is scarce. Records were often incomplete, and international trade was not as precisely tracked as it is today.

* Shifting Production: Tea cultivation and production were evolving rapidly in the 18th century. New regions were being developed for tea, and production in existing areas was fluctuating.

However, based on historical knowledge, it's likely that China and India were major tea producers in 1773.

* China: China had a long and established tradition of tea cultivation and production, dating back centuries. It was likely the leading producer at this time.

* India: While India's tea industry was still developing in the 18th century, its production was growing, and it was already an important source of tea.

It's important to note: Other regions, like Japan and Southeast Asia, also produced tea, but their scale was probably smaller compared to China and India in 1773.
