In 1539, King Tabinshwehti attacked the Mon people inhabiting Chiang Kran, but under Siamese rule. Chairachathirat "marched against Chiang Kran" with the aid of 120 Portuguese traders in Ayutthaya, and drove the Burmese back. The Portuguese were then allowed to build a church near the Takhian Canal to practice their religion.
