Answer:
Korea, Japan, and China heavily influenced one another.
Explanation:
Korea (both South and North Korea), Japan, and China (including Taiwan, Hong Kong and Macao) form part of East Asia (sometimes Mongolia is also included).
Historically, China has had a profound influence on other East Asian countries, including vocabulary and writing, as well as beliefs and / or religions. The heart of this region is formed by East China, the Korean Peninsula and Japan; these countries and territories have several points in common:
-a humid climate, more or less temperate (continental in the north and tropical in the extreme south) and conducive to agriculture (wheat and especially rice);
-millennial civilizations;
-a long-standing scripture based on sinograms;
-a spirituality associating Buddhism, Taoism and Confucianism.
The expansion of Chinese culture to the East (Korea and Japan) is estimated in the sixth century. The expansion to Mongolia and the West in the twelfth century with the Yuan dynasty of Mongol origin under the leadership of Genghis Khan.
