Marco Polo was one of the most famous European travelers to reach China. He came from Venice, Italy, and his stories about his travels fascinated Kublai Khan. Marco enjoyed special status in the country for about sixteen years. Kublai sent him on many fact-finding and business trips. For three of those years, Marco ruled the city Yangchow.
Because the Mongols had such a large empire, China prospered from increased overland trade. The Mongols also kept working on the shipbuilding of the Song dynasty and expanded seagoing trade. Products such as silver, spices, carpets, and cotton came from Europe and places from Asia, like Japan, Korea, India, and Souheast Asia. China shipped out tea, silk, and porcelain in return.
In 1271, Kublai Khan had become the new emperor of China. He gave Mongol rulers jobs in the Chinese government. Under Mongol rule, China reached it's height of wealth and power. Over time, the Mongols used many Chinese inventions and ideas, they used gunpowder and a Chinese weapon called a fire lance. This allowed them to be stronger in battle.
