19世纪末以来,外国人在我国西北频繁出入进行“考察”,掠走了不少珍贵文物。1927年春,当得知瑞典人斯文·赫定一行将再次进入我国西北地区时,引起了学术界的强烈关注,北京十多个学术团体立即开会,成立“中国学术团体协会”,委派刘半农和周肇祥与斯文·赫定交涉,并于4月26日顺利通过了组建“中瑞西北科学考察团”的协议。协议规定:一切考察工作要在中国学术团体协会的领导下进行,采集品归中国。这是我国现代科学史上的一件大事,它从此结束了外国人无视中国主权掠夺我国文物的耻辱历史。 Since the end of the 19th century, foreigners frequently visited the northwest of China for “inspection” and plundered many precious cultural relics. In the spring of 1927, when it was learned that the Swedish Sven Heding and his entourage were going to re-enter the northwestern region of our country, they aroused strong academic attention. More than a dozen academic groups in Beijing immediately held a meeting to establish the “Association of Chinese Academic Societies,” and appointed Liu Bannong and Zhou Zhaoxiang Negotiated with Sven Hedin on April 26 and passed the agreement on setting up the “Sino-Swiss Northwest Scientific Delegation” on April 26. The agreement stipulates that all inspection work should be conducted under the leadership of the Association of Chinese Academic Societies, and the products collected will be returned to China. This is a major event in the history of modern science in our country. It has thus ended the history of foreigners ignoring China's sovereignty and plundering China's cultural relics.
