It seems that a pretty solid candidate for that honor would be a fellow by the name of Michael Alphonsus Shen Futseng (沈福宗). he was the son of Chinese Christians, and was received by the court of James II between 1685 and 1688.
He left for Europe from Macao at the behest of and alongside Father Philip Couplet, the Procurer of Chinese Jesuits in Rome. Prior to arriving in Britain, he visited Rome and tried to receive a Papal blessing to conduct Mass in Chinese in 1684. He was subsequently received at the court of louis XIV that September, where he taught the Sun King to use chop-sticks and write several Chinese characters.
He became well known at the English court, and the painting above was actually made for James II personally by Sir Godfrey Kneller, who painted the likes of Charles II, James II, William III, Mary II, Anne, George I and George II. In fact Shen Futseng's portrait remains hanging the the Queens drawing room at Widsor. It is interesting to note that over the course of his travels, Shen apparently communicated entirely in Latin.
Shen left England in 1688 and sailed for Lisbon to join the Society of Jesus. There he remained until 1691, when he sailed for China once again. Tragically, he died en route off the coast of Mozambique.
