The first Pax Sinica of the eastern world by Han China coincided with the Pax Romana of the Western World by Rome. It stimulated the long-distance travel and trade in Eurasian history. The Pax Sinica and Pax Romana both eroded at about 200 AD.
Tang China (618–907) established a second Pax Sinica.[when?] This was considered one of the golden ages of China. The economy, commerce, culture, and science was flourishing and reached new heights. During the early Tang-era, most notably during Emperor Taizong's reign, the Chinese brought their nomadic neighbors to submission. This secured the safety and peace at the many trade routes. The Pax Sinica brought forth a new age for exchange via the Silk Route. The Chinese civilization became open and cosmopolitan to all people from near and far away. Many people from different backgrounds and denominations traveled to the capital of Chang'an. These included clerics, merchants, and envoys from India, Persia, Arabia, Syria, Korea, and Japan.
A resurgence of this term has happened in recent years, as the rise of China changes the geopolitical landscape in Asia. The view has been expressed that a renewed Pax Sinica in Central Asia may help maintain stability in the region.
