The communist takeover of mainland China led the Truman administration to expand the containment doctrine to include Asia. The fall of the Chinese Nationalist government and the establishment of the People's Republic of China under communist leadership in 1949 was a significant event that heightened concerns about the spread of communism in the region. This development, along with other events such as the Korean War and the expansion of Soviet influence in East Asia, further solidified the US policy of containing communism beyond Europe and into Asia.
I hope this helped!
