After the demise of Anouvong in Bangkok in February 1829, Emperor Minh Mạng was angered and summoned Chao Noy of Muang Phuan and his family to Huế. Chao Noy and his consort were executed on the orders of Emperor Minh Mạng at Huế. The whole court of Muang Phuan was detained in Huế and Muang Phuan was incorporated into Vietnamese direct rule as the Trấn Ninh (Hán tự: 鎮寧) Province. Minh Mạng sent a mission to Bangkok in March 1829, demanding the retributions of the instigators of the massacre of Vietnamese envoys at Nakhon Phanom. The Bangkok court replied that the incident was yet to be reported.
