Comment by tonytran2015: China has no valid claim to Siberia which has once been ruled by Mongolia who has also once ruled China. Should Japan take back China since Japan had once ruled China? (Understanding China’s Perpetual Wars against its neighbours, posted 2017 April 01.).
One day, China might want the globe to match the reality. In fact, Beijing could use Russia’s own strategy: hand out passports to sympathizers in contested areas, then move in militarily to “protect its citizens.” The Kremlin has tried that in Transnistria, Abkhazia, South Ossetia and most recently the Crimea, all formally part of other post-Soviet states, but controlled by Moscow. And if Beijing chose to take Siberia by force, the only way Moscow could stop would be using nuclear weapons.
There is another path: Under Vladimir Putin, Russia is increasingly looking east for its future – building a Eurasian Union even wider than the one inaugurated recently in Astana, the capital of Kazakhstan, a staunch Moscow ally. Perhaps two existing blocs – the Eurasian one encompassing Russia, Belarus and Kazakhstan and the Shanghai Cooperation Organization – could unite China, Russia and most of the ‘stans. Putin’s critics fear that this economic integration would reduce Russia, especially Siberia, to a raw materials exporter beholden to Greater China. And as the Chinese learned from the humiliation of 1860, facts on the ground can become lines on the map.
