evidence: China has always attached great importance to territorial integrity and has always adhered to the concept of fighting for every inch of land. However, in 1960, when it came to the territorial division between China and Myanmar, China gave up its territorial claim on Jiangxinpo on the Sino-Myanmar border. Since then, Jiangxinpo has completely become a territory of Myanmar. Of course, China is not without gains. The three towns of Gangfang, Gulang, and Pianma were occupied by the British in 1913, and they were successfully recovered in this demarcation. A total of 153 square kilometers. In addition, the two tribal jurisdictions of Banhong and Banlao that belonged to Myanmar in 1941 were assigned to China. This jurisdiction has a total of 189 square kilometers of land. But in fact, the direct reason why Myanmar is willing to give up these lands is that the value of Jiangxinpo far exceeds these lands. So what is the value of Jiangxinpo, located on the China-Myanmar border, as the gateway to the eastern part of southern Tibet?
