<u><em>China financed a large new fleet sent out to trade and build contacts under the command of Zheng He.</em></u>
Answer: Option C
<u>Explanation:</u>
- Ming dynasty is the one and only first Chinese dynasty that showed interest in trading with other countries. Zheng He was a great sea explorer who is also a fleet commander.
- He established trades with many foreign countries. He served under the third Emperor Yongle whose reign was between 1402 to 1424. He built big ships (some families can live in) also named them as Junk to travel in the sea.
- That made the Ming Dynasty earn more money. Ming Dynasty was interested only trading with Portuguese and Spain but most of the Europeans wanted to trade wit Asia for spices and teas.
- When Yongle died the funding for the travel was stopped and that was the end of the Ming Dynasty's International trade through seas.
