Boulder-Lhasa Sister City Project (BLSCP) is a non-profit 501(c)(3) public charity formed in 1986 in Boulder, Colorado, which develops and implements non-political exchanges of mutual benefit with Lhasa, Tibet, including surrounding areas. Since 2013, BLSCP has focused on alleviating suffering by rural Tibetans from parasitic diseases caused by the pork tapeworm. This work has been helping Tibetans living in Yajiang and Muli Counties of Sichuan Province (Kham).
