Seems Chiang simply observed the reality of the poor system of Russian communism way back in the 1920s, and that it would not be best....
Background only seems to support that view, so far as I see so far: e.g.:
"Chiang became a founding member of the Nationalist Party (a forerunner of the KMT) after the success (February 1912) of the
1911 Revolution. After the takeover of the Republican government by
Yuan Shikai and the failed
Second Revolution in 1913, Chiang, like his KMT comrades, divided his time between exile in Japan and the havens of the
Shanghai International Settlement. In Shanghai, Chiang cultivated ties with the city's underworld gangs, which were dominated by the notorious Green Gang and its leader Du Yuesheng. On 18 May 1916 agents of Yuan Shikai assassinated Chen Qimei. Chiang then succeeded Chen as leader of the
Chinese Revolutionary Party in Shanghai. Sun Yat-sen's political career reached its lowest point during this time – most of his old Revolutionary Alliance comrades refused to join him in the exiled Chinese Revolutionary Party.

...Sun regained control of Guangdong in early 1923, again with the help of mercenaries from
Yunnan and of the
Comintern. Undertaking a reform of the KMT, he established a revolutionary government aimed at unifying China under the KMT. That same year Sun sent Chiang to spend three months in Moscow studying the Soviet
political and military system.
During his trip in Russia, Chiang met Leon Trotsky and other Soviet leaders, but quickly came to the conclusion that the Russian model of government was not suitable for China. Chiang later sent his eldest son, Ching-kuo, to study in Russia. After his father's split from the
First United Front in 1927, Ching-kuo was forced[
by whom?] to stay there, as a hostage..."
