In 1353 Fa Ngum was crowned, and named his Kingdom "Lan Xang Hom Khao" "The Land of a Million Elephants and the White Parasol", Fa Ngum continued his conquests to secure the areas around the Mekong by moving to take Sipsong Panna (modern Xishuangbanna Dai Autonomous Prefecture) and began moving south to the borders of Lanna along the Mekong. King Phayu of Lanna raised an army which Fa Ngum overwhelmed at Chiang Saen, forcing Lanna to cede some its territory and provide valuable gifts in exchange for mutual recognition. Having secured his immediate borders Fa Ngum returned to Muang Sua.
