The Sino-Burmese War (; ), also known as the Qing invasions of Burma or the Myanmar campaign of the Qing Dynasty, was a war fought between the Qing Dynasty of China and the Konbaung Dynasty of Burma (Myanmar). China under the Qianlong Emperor launched four invasions of Burma between 1765 and 1769, which were considered as one of his Ten Great Campaigns. Nonetheless, the war, which claimed the lives of over 70,000 Chinese soldiers and four commanders, is sometimes described as "the most disastrous frontier war that the Qing Dynasty had ever waged", and one that "assured Burmese independence". Burma's successful defense laid the foundation for the present-day boundary between the two countries.
