The Vietnamese government fears that evidence of Champa's influence over the disputed area in the South China Sea would bring attention to human rights violations and killings of ethnic minorities in Vietnam such as in the 2001 and 2004 uprisings, and lead to the issue of Cham autonomy being brought into the dispute, since the Vietnamese conquered the Hindu and Muslim Cham people in a war in 1832, and the Vietnamese continue to destroy evidence of Cham culture and artifacts left behind, plundering or building on top of Cham temples, building farms over them, banning Cham religious practices, and omitting references to the destroyed Cham capital of Song Luy in the 1832 invasion in history books and tourist guides. The situation of Cham compared to ethnic Vietnamese is substandard, lacking water and electricity and living in houses made out of mud.
