Second, the Qing Dynasty and Russia were both feudal agricultural countries at that time, and the bitter Siberia was useless to the economies of both countries in that non-industrial era, and the control cost was too high! In the early industrial age, Siberia was still in ruins for Russian exiles. Tsarist Russia controlled Siberia in order to continue to look eastward for the sea ports in the Pacific Ocean-its basic national policy was to look eastward for the sea ports in the Far East, Iran and southeastern Afghanistan.
Third, the real comprehensive industrialization of Siberia was the result of Soviet industry moving eastward to avoid disaster during World War II. This is the great development of industry, agriculture and mining in Siberia.
Fourth, you think Siberia has resources today, but unfortunately it has not been occupied. The problem is that that place was useless to the Qing Dynasty. You think Siberia is now a treasure house of oil. In ancient times, China people used oil, but all of them were used as weapons. Different eras have different understandings. It is really wicked to kidnap Qing in the non-industrial era!
In other words, you can't kidnap people from the past with what you know today. If Japan detects Daqing Oilfield; If Hitler can dig up Libya's oil, I'm afraid world history will be rewritten (Japan doesn't have to rush south, Hitler must kneel down to protect Libya's oil completely first, so that Italy can even rise by oil). The problem is that the level of science and technology at that time did not allow Germany, Japan and Italy to find oil there.
