In the sixteenth century Portuguese, Spanish, and Dutch merchants and adventurers began to participate in the East Asian maritime world (see Chapter 16). The trade between Japan, China, and Southeast Asia was very profitable, and the European traders wanted a share of it. They also wanted to develop trade between Asia and Europe.
The Portuguese and Dutch were not reluctant to use force to gain control of trade, and they seized many outposts along the trade routes, including Taiwan. Moreover, they made little distinction between trade, smuggling, and piracy. In 1521 the Ming tried to ban the Portuguese from China. Two years later an expeditionary force commissioned by the Portuguese king to negotiate a friendship treaty defeated its mission by firing on Chinese warships near Guangzhou. In 1557, without informing Beijing, local Chinese officials decided that the way to regulate trade was to allow the Portuguese to build a trading post on uninhabited land near the mouth of the Pearl River. The city they built there — Macao — became the first destination for Europeans going to China until the nineteenth century, and it remained a Portuguese possession until 1999.
European products were not in demand in China, but silver was. Japan had supplied much of China’s silver, but with the development of silver mines in the New World, European traders began supplying large quantities of silver to China, allowing the expansion of China’s economy.
Chinese were quick to take advantage of the new trading ports set up by European powers. In Batavia harbor (now Jakarta, Indonesia) Chinese ships outnumbered those from any other country by two or three to one. Manila, under Spanish control, and Taiwan and Batavia, both under Dutch control, all attracted thousands of Chinese colonists. Local people felt the intrusion of Chinese more than of Europeans, and riots against Chinese led to massacres on several occasions.
A side benefit of the appearance of European traders was New World crops. Sweet potatoes, maize, peanuts, tomatoes, chili peppers, tobacco, and other crops were quickly adopted in East Asia. Sweet potatoes and maize in particular facilitated population growth because they could be grown on land previously thought too sandy or too steep to cultivate. Sweet potatoes became a common poor people’s food.
