5 . Marco Polo’s tales inspired European explorers to search for sea routes (路线) from west to east. However, businessmen and explorers from the East set sail from east to west many years before Columbus first did.

In ancient times, silk from China found its way over land to India, the Middle East, and Rome, along what became known as the Silk Road. But another trading route across the sea was also formed along the coasts of the Indian Ocean, centered around Ceylon. Here, businessmen from China and many other places met to exchange goods.

Later, the Ming Dynasty further developed relations with these regions. Between 1405 and 1433, seven large fleets (舰队) sailed west on voyages of trade and exploration. Under the command of Zheng He, they set sail from the South China Sea across the Indian Ocean to the mouth of the Red Sea, and then to the east coast of Africa. African royal families sent gifts such as giraffes as gestures of friendship in return for silk, and spices. Although China stopped further expeditions (远征) after 1433, these land and sea routes remained active for centuries.

To reach out across the sea remains a strong desire today. The ancient sea routes travelled by Zheng He are being revisited with the 21st Century Maritime Silk Road, which is part of the Belt and Road Initiative (一带一路倡议). The aim of this initiative is to encourage cooperation and trade across the historic Silk Road areas, and strengthen the relations between China and the rest of the world. China has poured billions of money in systems and services along these routes, which will help to greatly develop the whole area for the benefit of future trade and cultural exchange.

China has also joined its friends across the sea on other important projects. In recent years, China has joined other nations on several expeditions to explore the Arctic. From a scientific point of view, there is an urgent need to study the Arctic in order to understand climate change and its effects.
