Let's start with China, the world's most populous state with more than 1.4 billion people, most of whom get their news on Ukraine from the state-controlled media, just as most people do in Russia. China received a high-profile visitor to its Winter Olympics shortly before the Ukraine invasion began on 24 February - President Putin. A Chinese communique issued afterwards said there "was no limit to the two countries' co-operation". So did Putin tip off his Chinese counterpart Xi Jinping that he was about to launch a full-scale invasion of Ukraine? Absolutely not, says China, but it's hard to imagine that there would have not been even just a hint of what was to come to such an important neighbour.
