Which was the first Asian nation to become communist?

The first Asian nation to become communist was the Soviet Republic of Mongolia, which declared itself a communist state in 1924 after a revolution that was influenced by the Bolshevik Revolution in Russia. However, China is often more prominently recognized for its communist revolution, which culminated in the establishment of the People's Republic of China in 1949 under the leadership of the Chinese Communist Party. Both nations played significant roles in the spread of communism in Asia.
