The Portuguese reached India in 1498, conquered Malacca in 1511 and in 1512 António de Abreu and Francisco Serrão reached the Spice Islands. In May 1513 Jorge Álvares reached southern China and in the same year Balboa crossed Panama. In 1525 Diogo da Rocha and Gomes de Sequeira reached the Caroline Islands, and Jorge de Menezes in 1526-27 landed on the "Islands of Don Jorge de Menezes", in the northwest coast of New Guinea (now part of Indonesia), and named the region "Ilhas dos Papuas" and is thus credited with the European "discovery" of Papua. In 1542 Fernão Mendes Pinto reached Japan. From about 1543 until 1614, the Portuguese monopolize the trade between China and Japan, through the nanban trade. In 1589, João da Gama reached Hokkaido and possibly sighted the Kuril islands, crossing the Pacific further north of the routes usually taken until then. The land that he eventually discovered northeast of Japan, has since become a matter of legend and controversy.
