After being created Earl Macartney in the Irish peerage in 1792, he was appointed the first envoy of Britain to Qing China, after the failure of a number of previous embassies, including Cathcart's. He led the Macartney Embassy to Beijing in 1792, with a large British delegation on board a 64-gun man-of-war, under the command of Captain Sir Erasmus Gower. The embassy was ultimately not successful in its primary aim to open trade with China, although numerous secondary purposes were attained, including a first-hand assessment of the strength of the Chinese empire.
