As the entire country of China has fallen under communist rule in the Chinese Civil War of the 1940s, we would all expect the history of death and murder the CCP has conducted. This is, obviously, something to expect, the consequences, but not the result. The KMT had more men than the communist rebels, and they were better trained, by German and American generals, while the communists were secretly supplied by the Soviets. Still, the KMT had a huge afvantage over the CCP, just like the Brits with the American colonists, or the Northeners with the Dixie people in the American Civil War. What if the KMT had won the Civil War?
1. Economically: the KMT would've led the ROC to an economic and industrial boom in the 1980s. As in this timeline, Made in Taiwan products were becoming popular, it'd not be a surprise to see an economic boom in this alternate timeline. The Republic of China would become a place for foreign investments for industrial manufacturing, and, with a right-wing party in power, the Kuomintang, that hopes to attract economic foreign investment, then I see this coming for a democratic right wing China in the 1980s, way earlier than Deng Xiaoping's reforms.
2. Socially: China would become a very closed-minded country about foreigners. Just like today, China doesn't welcome people from other places that openly. It prefers to stick to thier own and live in a Chinese China. This shows China would become, just as today, a very conservative society, even with LGBT issues, except in the big cities like Beijing and Shanghai, which would become economic centers in the country, which usually leads to liberalism and social reform. Meanwhile, in the countryside, people would still be very unwelcome to gays and foreigners.
3. Militarily: a democratic and free China would have a big military, especially with Jiang Jieshi winning the Chinese Civil War, who is a militaristic man. A big military would stay under the ROC's hands, not bigger than today's, but big enough to take on another foreign power. Still, KMT soldiers would have way more military experience than today's. Today's China does not actively send their soldiers to a war, since it does not want to...
