What measures did the Tang Dynasty take to strengthen relations with ethnic minorities and maintain the stability of the border areas? Explain with relevant historical facts.

The main ways are 1, marriage, such as Princess Wencheng and Princess Jincheng entering Tibet.

2. Establish institutions to manage the border minority areas, such as the governor of Anxi and the governor of Beiting.

3. Destroy East and West Turkestan by force.

4. Confess minority leaders. For example, Emperor Xuanzong of the Tang Dynasty successively conferred the title of Huihe leader Guli Peiluo as Huairen Khan, Hou Ji leader Da Luorong as the king of Bohai County, and Nanzhao leader Pirog as the king of Yunnan.

The Tang government pursued a relatively friendly foreign policy. In 64 1 year, Emperor Taizong sent someone to escort Princess Wencheng to Tubo to marry Zambizong Zambopo. Later, Princess Jincheng married Zambezi Dezuzan and formed an alliance to bring the advanced culture of the Tang Dynasty to Tubo. In 822, the Tang-Fan Alliance was established, and the boundaries were demarcated and non-aggression. The Jokhang Temple in Lhasa still preserves the monument of the Tang-Fan Alliance. In 794, the Tang Dynasty and Nanzhao joined forces in Diancang Mountain, and the two sides established good relations.
