Sa Pa
In the following decade, the future site of Sa Pa township started to see military parties as well as missionaries from the Société des Missions Etrangères de Paris (MEP) visit. The French military marched from the Red River Delta into the northern mountainous regions as part of Tonkin's ‘pacification’. In 1894-96 the border between China and Tonkin was formally agreed upon and the Sa Pa area, just to the south of this frontier, was placed under French authority. From 1891 the entire Lào Cai region, including Sa Pa, came under direct colonial military administration so as to curtail banditry and political resistance on the sensitive northern frontier.
