evidence: Aksai Chin is disputed between India and China since the formation of India and it goes back to the nineteenth century. William Johnson, a civil servant with the Survey of India, proposed "Johnson Line" in 1865, which put Aksai Chin in Kashmir. This map was not shared with China. The moot question is why not? Because Xinjiang prefecture at that time was not under the control of China. It came under Chinese control years later and it was not until 1892 when China erected boundary markers at Karakoram pass. [...] In the 50s, PLA outposts were constructed in Tianwendian, Kongka Pass, Heweitanand Tianshuihai etc. Indian Army did point out these developments to New Delhi, but then Hindi-Chini Bhai Bhai was gaining voice and no one wanted to bell the cat. In the meantime, this road was upgraded to China National Highway 219. These days it is called G219 and it goes through the India claimed region of Aksai Chin. First incident of stone throwing at Indian Army by PLA happened in 2017. It is an important year for the region because in 2010, China conducted geological surveys in Western Kunlun region, which Aksai Chin is part of. Lo and behold in Huoshaoyun, a major lead-zinc deposit, and numerous smaller deposits were discovered. Huoshaoyun is a mountain located in Aksai Chin near the Tibetan border. Mining development of Huoshaoyun started in 2017 and Chinese PLA started pelting stones and started stronger assertions to this strategic piece of land.
