From Morocco to France, from finance to chess, from economics to geopolitics, from literature to mathematics, these texts have taken shape in a world of growing complexity. A world that, let's not forget, is suffering from numerous crises whose impacts are significant. We'll be focusing on the global water crisis and associated water stress, the inflation crisis, the war in Ukraine and its consequences for international geopolitics, the banking and financial crises, and the chip and semiconductor crisis. Particular attention will be paid to the Middle Kingdom, China, which is very present on the world stage and no longer hides its ambitions. The complicit and complex ties between Beijing and Moscow, tensions with Washington, the thorny Taiwan issue and Chinese investment in Africa will also be discussed.
