The Guangnan West Circuit Fiscal Commissioner, Wang Han (fl. 1043–1063), feared that Nùng Trí Cao's kinsmen Nùng Tông Đán intended to plunder the region after he crossed the Song border in 1057. Wang Han took a personal visit to Nùng Tông Đán's camp and spoke with Nùng Trí Cao's son, explaining that seeking "Interior Dependency" status would alienate them from the Vietnamese, but if they remained outside of China proper they could safely act as loyal frontier militia. Wang Han then sent a memorial to Emperor Renzong's (r. 1022–1063) court in 1060, advocating the policy agreed with the Nùng. The Song government rejected his proposal and made the Nùng communities (along with other ethnic groups) official dependents of Song imperial authority, and Nùng Tông Đán's request that the territories under his authority be incorporated into the Song Empire was granted in 1062. In 1059—six years before the Song court's New Policies under Chancellor Wang Anshi (1021–1086) organized new self-sufficient militia units throughout the empire and along the border with Đại Việt—the Vietnamese ruler Lý Thánh Tông reorganized northern frontier administrative units and raised new militias. This bolstered his kingdom's strength in a time of conflict with Champa (located in southern Vietnam).
