When did asians first begin migrating to the guianas in large numbers?

1492, when Christopher Columbus sailed the Atlantic, he expected to reach Asia, and in 1519 Ferdinand Magellan started his voyage that was, after Magellan’s death, to circumnavigate the world, sailing through what became the Straits of Magellan across the Pacific Ocean, proving that it was possible to make the voyage.

However, there was little migration from Asia to the Americas until the early 19th century. Few Chinese ventured overseas during this period, except for those already in Southeast Asia—the Nanyang, as they called it.

In 1637 the Japanese government banned travel overseas and requested their citizens to return home; Korea was so isolated that travel was extremely difficult until recently. It is probable, however, that some Filipinos did settle in Latin America, especially in Peru, the center of Spanish power, as there were close shipping ties between Lima and Manila.
