Although shipping was regulated, the Qianlong emperor's administration was diligent in accommodating the requisites of Western merchants. They hired a growing body of Western assistants for the Customs Office to help manage their fellow countrymen. The order to stay in Macao during the winter was lifted, tax was exempted on food, drink and basic supplies for Western merchants, and protections were granted to Westerners and their property. Chinese merchants were actually banned by Qing law from suing foreigners in Chinese courts, as the Qianlong Emperor believed that good treatment of foreigners was essential for the government. In 1806, Chinese officials compromised with the British on the murder of a Chinese man by British seamen, as Westerners refused to be punished under Chinese law, even though local citizens vigorously protested what they considered a miscarriage of justice. In 1816, the Jiaqing Emperor dismissed a British embassy for their refusal to kowtow, but he sent them an apologetic letter with gifts (the British simply discarded them in a storeroom without reading). The Qianlong Emperor granted Lord Macartney a golden scepter, an important symbol of peace and wealth, but this was dismissed by the British as worthless. The British, on the other hand, ignored Chinese laws and warnings not to deploy military forces in Chinese waters. The British landed troops in Macao despite a Chinese and Portuguese agreement to bar foreign forces from Macao, and then in the War of 1812 attacked American ships deep in the inner harbour of Canton (the Americans had previously robbed British ships in Chinese waters as well). These, in combination with the British support to Nepal during their invasion of Tibet and later the British invasion of Nepal after it became a Chinese tributary state, led the Chinese authorities to become highly suspicious of British intentions.
