The British Foreign Office sharply criticized Medhurst and Alcock for having used gunboats to extract concessions from the Nanjing Viceroy. This was contrary to the British policy of holding the central government of China - not local governments - responsible for enforcing the commercial treaties and the safety of foreign residents in China. The incident prompted foreign secretary Lord Clarendon to officially censure Medhurst and Alcock for the actions, and to reiterate the policy of the British government to seek redress from Beijing whenever foreigners were attacked.
