He worked with Sir George Staunton in producing the official account of the British mission to the Chinese Imperial court. This diplomatic and trade mission was headed by George, Earl Macartney. Although the Macartney Embassy returned to London without obtaining any concession from China, the mission could have been termed a success because it brought back detailed observations. This multivolume work was taken chiefly from the papers of Lord Macartney and from the papers of Sir Erasmus Gower, who was commander of the expedition. Banks was responsible for selecting and arranging engraving of the illustrations in this official record.
