As ever, Beijing and Moscow are stepping in to support a regime falling foul of the west. China and Russia have long acted in a sort of harmony together on the world stage. They back each other up in the UN Security Council, and have a similar outlook on the world, fearing messy democratisation driven by western governments and NGOs. But underlying this is a tension; the two countries have a common aim, yet they still distrust each other. Russia, in particular, fears the way the scales in their relationship have increasingly tipped in Beijing’s favour. Beijing, in turn, worries about Moscow’s reliability, fearing it might abruptly turn westward.
