Zhihua Shen and Yafeng Xia 7 On April 25,1958,the MFA notified border provinces and autonomous regions that border disputes with China's neighbors would gradually be resolved.The MFA stated that in view of the complication of border disputes,the MFA,in conjunction with relevant departments,had started to review the issue.The MFA ordered the foreign affairs divisions of provincial and autonomous regions'governments to appoint special personnel to play a sup- porting role in the effort,pointing out that the study should focus on undefined boundaries and controversial issues in defined boundaries (Jilin Provincial Archive,folder 77/4/1).
