How and why did communism fall in Asian countries after the Cold War? How did Asian countries grow economically after the Cold War? How and why did economic growth become an opportunity? Which countries became economically successful (besides the U. S. and European countries) ?

Communism never fell within Asian countries after the cold War. Technically some did but none of extreme relevance. The DPRK, Vietnam, CCP (China), Laos and others still remain communist. However places like Turkmenistan, Kazakstan, Tajikistan, and other USSR occupied territories within Asia had become democratic or anocratic to some degree. Places like Indonesia and Myanmar and places with heavy socialist ideas had progressed and incorporated some of it into their constitutions and laws without defaulting to that way of life.

Explanation:

Economic growth became an opportunity as it creates jobs, spurs market growth, development of a nation in all regions. Japan, South Korea, Taiwan (kind of), and Especially Singapore all gained extreme amounts of wealth throughout the Cold War and gained even more relevance onto eastern markets with the Fall of the communists.
