I agree. His motivations were not bad such as save China but in that time they did not have a stable government, so it was not good for them all.
When Chiang returned to China in 1911, he participated in a revolution that ended the Qing Manchu dynasty, which then reigned in the country. With that, it transformed China into a republic. However, for many years there was no stable government, as some feudal warlords, who dominated the provinces, fought for power.
After a period of study in the Soviet Union, Chiang returned to China in 1923. Two years later, he replaced Sun at the helm of the Kuomintang (Nationalist Party). At that time the Communists were part of the Nationalist Party, but in 1927 Chiang Kai-shek expelled them from it. Chiang also rose up against the warlords and, in 1928, established a new government. Warlords and Communists, however, continued to oppose him.
When Japan invaded China in 1937, Chiang made a temporary alliance with the communists to fight the invaders. This struggle became part of the larger World War II conflict. After the Japanese surrender in 1945, the Communists turned against Chiang again. In 1949 they defeated him and founded the People's Republic of China. Chiang Kai-shek transferred his nationalist government to the island of Taiwan, where he died on April 5, 1975.
The word Vietnam is derived from two Chinese words meaning "the Viet kin in the South". Traditionally, the people of Vietnam have been regarded by westerners as staunchly xenophobic, and, as such, have been viewed as having a long standing contempt for Chinese influence on the region. Border and island disputes have only exacerbated long-standing tensions between the two nations. Vietnam and China share many common cultural traditions which originated from the wet rice cultivation. China controlled Vietnam for about 1000 years, a rule which ended in 939CE. Thus, Vietnamese culture, writing, politics, religion, etc. were sinicized to a a certain degree. Yet the degree to which Vietnam preserved a distinct identity and maintained separate traditions should also be noted. During the 1st and 2nd Indochinese Wars, Vietnam grew closer to PR of China and received some funding, material, and advisors from the PRC. However, war with China in 1979 renewed hostilities. the reason why Vietnam and china are close because is that they are both communism country, there isn't much comminusim country left in the world
