In the 17th century, the Dutch, English and, after the 1680s, the French, competed for the opportunity to trade with the island of Phuket (then known as "Jung Ceylon"), which was a rich source of tin. In September 1680, a ship of the French East India Company visited Phuket and left with a full cargo of tin.
A year or two later, the Siamese King Narai, seeking to reduce Dutch and English influence, named as governor of Phuket a French medical missionary, Brother René Charbonneau, a member of the Siam mission of the Société des Missions Etrangères. Charbonneau remained as governor until 1685.[5]
