The crusades and the travels of kublai khan increased trade and travel in the middle ages  ? is this true or false

True

Kublai Khan was the fifth Khagan of the Mongol Empire, reigning from 1260 to 1294. He also founded the Yuan dynasty in China and ruled as the first Yuan emperor until 1294. The Yuan dynasty ruled over present-day Mongolia, China, Korea and some adjacent areas.

Under Kublai, direct contact between East Asia and Europe was established. This was because the central Asian trade routes were under Mongol control. Moreover, this was facilitated by the presence of efficient postal services. During the early 13th century, Europeans and Central Asians travelled to China, while large numbers of Chinese travelled to other parts of the Mongol Empire, Russia, Persia and Mesopotamia.
