The failure to obtain trade concessions was not due to Macartney's refusal to kowtow in the presence of the Qianlong Emperor, as is commonly believed. It is probably described most neutrally as a result of competing world views which were uncomprehending and incompatible. After the conclusion of the embassy, Qianlong sent a letter to King George III, explaining in greater depth the reasons for his refusal to grant the requests of the embassy. The Macartney Embassy is historically significant because it marked a missed opportunity by the Chinese to move toward some kind of accommodation with the West. This failure would continue to plague the Qing Dynasty as it encountered increasing foreign pressures and internal unrest during the 19th century.
