Also I alway find the WWII scenario in that they greatly understrength China. In all the PBEM I played ( about 3 or 4) not once did China make any serious stand before being overrun by Japan. In reality though, China should be harder to take

"By 1940, the fighting had reached a stalemate. While Japan held most of the eastern coastal areas of China, guerrilla fighting continued in the conquered areas. The Nationalist government of Chiang Kai-shek struggled on from a provisional capital at the city of Chongqing; however, realizing that he also faced a threat from communist forces of Mao Zedong, he mostly tried to preserve the remaining strength of his army and avoid heavy battle with the Japanese in the hopes of defeating the Communists once the Japanese left. China, with its low industrial capacities and limited experience in modern warfare, could not launch any decisive counter-offensive against Japan. Chiang could not risk an all-out campaign given the poorly-trained, under-equipped, and disorganized state of his armies and opposition to his leadership both within Kuomintang and in China at large. He had lost a substantial portion of his best trained and equipped army defending Shanghai and the remaining troops were used to preserve his army. On the other hand, Japan had suffered tremendous casualties from unexpectedly stubborn resistance from China and already developed problems in administering and garrisoning fallen territories. Neither side could make any swift progress in a manner resembling the fall of France and Western Europe to Nazi Germany."
The game begin at 1941 where the fight have basically come to a stalemate.
"Because of Chiang Kai-shek's anti-communist nationalist policies and hopes of defeating the CCP, Germany provided the largest proportion of Kuomintang arms imports. German military advisors modernized and trained the Kuomintang armies; Kuomintang officers (including Chiang's second son, Chiang Wei-kuo) were educated in and served in the German army prior to World War II. More than half of the German arms exports during its rearmament period were to China. Nevertheless the proposed 30 new divisions equipped with all German arms did not materialize as the Germans sided with the Japanese later in World War II.
Other prominent powers, including the United States of America, the United Kingdom, and France, only officially assisted in war supply contracts up to the attack on Pearl Harbor in late 1941, when a significant influx of trained military personnel and supplies boosted the Kuomintang chance of maintaining the fight."
They are also specially trained soldiers from other powers those there should be specially trained soliders for Chinese to represent that.
Perhaps a bit more autoproducing unit wonders?
I guess what's also largely undermine is the gurellia forces that did not exist in TOS and Communist China poses no actually threat as it's not really active at all.
Not to say though that Chinese is still underequip, doesn't really receive whole bunch of equipments and such. But I think they should have a higher population base to represent their huge populations which is not reflected right now.
