Ok-khun Chamnan

Ok-khun Chamnan Chaichong was a Siamese diplomat who visited France and Rome on an embassy in 1688. He was preceded by the embassy of Kosa Pan in 1686.

Failed embassy to Portugal (1684) Ok-khun Chamnan was a member of a first embassy to Portugal, which left Siam in March 1684. The Siamese embassy was accompanying a returning Portuguese embassy, which had been sent to Siam by king Pedro II.

The embassy was returned to Siam by the six warship fleet of Abraham Duquesne-Guiton (nephew of the famous Abraham Duquesne) in 1690, but because of unfavourable winds the fleet was only able to go as far as Balassor, at the mouth of the Ganges, where they dropped the embassy. The embassy finally returned to Ayutthaya overland.
