Analyze how cultural diffusion impacted east asia south asia and southeast asia

The ancestors of modern Southeast Asian people arrived from Tibet and China about 2,500 years ago, displacing the aboriginal groups that occupied the land first. They subsisted on rice and yams which they may have been introduced to Africa.

Southern Chinese culture, agriculture and domesticated animals (pigs, chickens and dogs) is believed to have spread from the Philippines through the islands of Indonesia to the islands north of New Guinea. By 1000 B.C., obsidian was being traded between present-day Sabah in Malaysian Borneo and present-day New Britain in Papua New Guinea, 2,400 miles away. Later southern Chinese culture spread eastward across the uninhabited islands of the Pacific, reaching Easter Island (10,000 miles from China) around 500 A.D.
