Sir James William Ronald Macleay GCMG (1870 – 5 March 1943) was a British diplomat.
Macleay was educated at Charterhouse School and Balliol College, Oxford, and entered diplomatic service in 1895.
[1] He served in Washington, D.C., Constantinople, Mexico City and Brussels, among other postings.
[3] His period as ambassador to China was criticized, and although Macleay was favorable to American ambassador John Van Antwerp MacMurray, it was not reciprocated; MacMurray described him as "a Tory of the type that neither imagined good could come out of any liberal ideas hatched at Washington under the auspices of the American rebels, nor perceived within China itself had been developing ideas which had already challenged and movements which had undermined British primacy.
"[2] In 1927 he became British Minister to Czechoslovakia until 1929 and in 1930 until 1933 returned to his post as Ambassador to Argentina.
