China was and still is a very immense country.  It was extremely influential towards all of the counties around it, especially towards Korea, Vietnam, Khmer, and Japan.  Because of China being a very close neighbor to all of these countries, its culture easily spread towards them.  In 108 B.C., the Chinese, during their Han Dynasty, invaded Korea and spread their ideas everywhere.  The Koreans banned together and rebelled against the Chinese, driving them out of Korea.  By 75 B.C., the Koreans had won back close to all of their lands from the Chinese.  The Koreans then became three seperate kingdoms over the next 700 years.  The Silla kingdom of the south conquered the other two kingdoms.  The Silla kingdom drove out the remaining Chinese and regained all of their land back.  Later, the Silla kingdom fell and was then ruled by a kingdom named Koryo.  Korea received its name after the Koryo kingdom.  The Koryo rulers were greatly impressed by the Chinese and decided to create their government similar to China's.  Koreans learned much from the Chinese, too.  They learned of rice cultivation, papermaking, and printing.  In cultural aspects, the Koreans learned forms of Chinese art and pottery.  With belief systems, the Koreans adopted two of them.  They were Buddhism and Confucianism.  Korea was the actual passers of Buddhism from the Chinese to the Japanese.  In 111 B.C., the Chinese conquered the Vietnamese and demanded that they adopt many of the Chinese cultures.  Some Chinese ideas the Vietnamese had to adopt were speaking Chinese, wearing the Chinese clothes,  and following Confucianism and Daosim.  In A.D.40, the Vietnamese were successful and two female rulers at the time were slowly driving the Chinese out.  During this time, the Vietnamese continued to adopt many Chinese cultures, but also tried to drive the Chinese out of their territory.  In the 900's, the Vietnamese finally succeeded and drove the remaining Chinese out of their country.  The Khmers were a people south of China and had established a kingdom called Khmer.  The Khmers learned much about rice cultivation from the Chinese, but most of the cultural aspects came from their western neighbor India.  They were so greatly influenced by India that they learned of rule by a god-king, their writing system, and Hinduism and Buddhism.  Out of these three countries, it is safe to say that Korea most willingly adopted the most of the Chinese ideas.
