This miniature stamp sheet of Mongolia shows the portrait of the Great Mongol Emperor of 12th Century, and the founder of Yuan Dynasty in China - Kublai Khan and a sailing warship of his period.
Kublai Khan twice attempted to invade Japan. It is believed that both attempts were thwarted by bad weather or a flaw in the design of ships that were based on river boats without keels, and his fleets were destroyed. The first attempt took place in year 1274, with a fleet of 900 ships. After the first Mongol attack on Japan, Japanese pirates known as Wokou raided Korea, but Mongol-Korean forces pushed them back, and the Wokou pirates decreased their activity due to the increased military preparedness of the Goryeo and the Kamakura. In 1293 the Yuan navy captured 100 Japanese people from Okinawa.
The second invasion occurred in year 1281 when Mongols sent two separate forces; 900 ships containing 40,000 Korean, Chinese, and Mongol troops were sent from Masan, while a force of 100,000 sailed from southern China in 3,500 ships, each close to 240 feet (73 m) long.
Kublai Khan also invaded Đại Việt (Vietnam) three times.
Three expeditions against Burma, in 1277, 1283 and 1287, brought the Mongol forces to the Irrawaddy Delta, whereupon they captured Bagan, the capital of the Pagan Kingdom in Burma, and established their government.
