During the years of Mongol rule, China entered into a trade agreement with what European city?

Paris

Constantinople

Rome

Genoa

Genoa

Explanation:

This exchange accounts for Marco Polo reaching China during this era. Ibn Battuta, the great Islamic traveler from Morocco, and Rabban Sauma, a Nestorian, or Assyrian, Christian from near Beijing, reached Europe and had audiences with the kings of England, France, and the Pope. A trade agreement was in place with the Italian city of Genoa. From this period on, historians speak about a Eurasian, if not a global, history. Developments in one part of Europe would now have an impact in Asia and vice versa. Global history begins, to some extent, with the Mongols who were able to build a bridge connecting the West with the East.

pretty sure it would be Paris
