Often, Great Britain, the United States and the Soviet Union got most of the recognition for the contributions to World War II. However, these countries were not the first to mount a resistance against the Japanese troops. In fact, China was the first nation to confront the then menacing Japan. The other countries joined the war in August 1945, months before it ended.
Apparently, the contribution of the Chinese army was overlooked because it was perceived as an inconvenience by the perpetrators of the Cold War. Back then, China had meager resources as compared to powerhouses such as Britain and the US. Despite this, the country sent over 40,000 soldiers to fight alongside Americans and Britons in Burma in 1944. This had a significant impact on the outcome of the war.
At the beginning of the 20th century, China decided to defend the sovereignty of its territories. For this reason, they had to confront the Japanese who were enforcing their imperialistic ideologies on the Asian mainland. As a result of the tension between the two parties, war ensued. The battle started in July 1937, lasting for eight years until the end of World War II. During the war, both the Nationalists under Chiang Kai-shek and the Communists under Mao Zedong fought against the Japanese.
