Lai Châu ({{audio|Lai_Châu.ogg|listen|help=no}}) is a city in the Northwest region of Vietnam. It is the capital city of Lai Châu Province. The city borders Phong Thổ District, Sìn Hồ District và Tam Đường District.
History
Lai Châu, or Muang Lay (Vietnamese: Mường Lay) was the seat of lords of the White Tai who were dominant over other Thai peoples of the area, though there was rivalry between the White Tai rulers of Muang Lay and Muang So.Michael C. Howard, Kim Be Howard Textiles of the Daic peoples of Vietnam Page 75, 2002 "In general the White Tai nobles in the north were dominant, but even among them there was intense rivalry between the rulers of Muang Lay and Muang So. In the 1870s and 1880s Chinese bandits known as Haw (or Ho) moved into northern ..." During the 1870s Muang Lay was the base of lord Đèo Văn Trị of the White Tai who sought to unite and become chief of the 12 mường (Sino-Vietnamese: {{lang|vi|Châu}} / {{lang|zh|{{linktext|州}}}}) making up the Sip Song Chau Tai. This he partially achieved, with the help first of the Chinese Black Flags, then later the French. His authority, and the autonomy of the area, was recognised by the French in 1890.
