Answer:
The correct answer to the question: What was a difference between Chinese and Portuguese navigation? would be: The Chinese were not looking to discover new places.
Explanation:
The Age of Exploration, between the 1400´s and the 1600´s was a very particular period in history in which many great powers of the world decided to place their focus on exploration through the sea, especially European nations who wished to reopen the trade routes to the East since the Ottoman Empire had closed the land routes to Asia. Thus, voyages like those of Dias, or Vaso de Gama from Portugal to round the tip of Africa, and Christopher Columbus to the Americas, were the opening to the discovery of new and unknown horizons. However, there was another power in the East who also used sea voyages, but not to discover anything, or establish colonies, but rather, to display their treasures and gain respect for their ruling dynasty, the Ming; this was China. The Chinese did not wish to discover anything; they much rather show other countries their vast wealth and their sea power as they had one of the most advanced and numerous fleet in the world.
