Towards the end of the article it mentions that China may be willing to absorb the tiny nation of 5 million people. While there are some mineral resources in the offering, Beijing wouldn't want the additional responsibility. It has enough on its hands with Xinjiang, Tibet, and the central provinces that still lag behind the coastal areas by a substantial margin. One of my classmates who is familiar with Central Asian and Russian affairs dismisses the article as a Russian grab for the territory, instead saying it could go to Tajikistan.
So in the future folks, when curious about what would Beijing do, follow these steps:
1) Remove any biases (pro or con) you have about China
2) View it from the Chinese perspective
3) Think what would best fit their interests in developing (hint: it's stability)
