In the 16th century, Lê Anh Tông of the Lê Dynasty encouraged traders to visit Vietnam by opening up Thăng Long (Hanoi), Huế and Hội An. Chinese presence in the Huế/Hội An area dated back as early as 1444, when a monk from Fujian built the Buddhist temple, Chua Chuc Thanh. Hội An quickly developed into a trading port from the 16th century onwards, when Chinese and Japanese traders began to arrive in the city in greater numbers. When an Italian Jesuit priest, Father Christofo Borri, visited the city in 1618, he aptly described the city as: "The city of Faifo is so vast that one would think it is two juxtaposed cities; a Chinese city and a Japanese city." The Japanese traders quickly disappeared by the first half of the 17th century as Tokugawa shogunate imposed a policy of self-isolation and when Dutch traders such as Francisco Groemon visited Hội An in 1642, the Japanese population was no more than 50 people, while the Chinese numbered some 5,000 individuals.
