The Chinese part of the Andersson collections, according to a bilateral Sino-Swedish agreement, was returned by him to the Chinese government in seven shipments, 1927–1936. The first shipments were sent by Andersson to Peking, and the last ones to Nanjing, which had become the new capital of China. An exhibit with these objects was mounted at the new National Geological Survey complex in Nanjing, where Andersson saw them in 1937, the last time they were reported seen by anyone. The last documentary evidence of these objects was a 1948 Visitors Guide to the Geological Survey museum in Nanjing, which listed Andersson's Yangshao artefacts among the exhibits. The objects were long thought to be irretrievably lost in the civil war that followed, until 2002. After major renovations at the Geological Museum of China, the successor to the Geological Survey's museum, staff found three crates of ceramic vessels and fragments while re-organising items in storage. Following contact with the Museum of Far Eastern Antiquities (Östasiatiska Museet) in Stockholm, it was confirmed that these were indeed left from Andersson's excavations. In 2006, these objects featured in an exhibition at the Geological Museum on the occasion of its 90th anniversary, celebrating the lives and work of Andersson and its other founders. In 2007, the Geological Museum of China published a documentary film (see review and discussion in Fiskesjö 2010). Still, as of 2010, the vast majority of the objects returned to China by Andersson remain lost. This includes a spectacular and unique human-faced ceramic shaman head (see illustration in Fiskesjö and Chen 2004, repeated in Fiskesjö 2010), and numerous spectacular painted ceramic vessels. Even though similar such ceramics have been excavated since Andersson's time by Chinese archaeologists, these lost collections hold a special interest and value since they derive from the first scientific archaeological excavations in China. It is possible they remain in Nanjing, but despite investigations by several competent parties (Andersson's sending lists have been copied by the Museum of Far Eastern Antiquities to major institutions for cultural heritage and archaeology in China), they have not been relocated, and their whereabouts remains unknown.
