Abstract
The article analyzes the main parameters of the modern world development, its architectonics and the most important development trends. Modern communications and principles of interaction of various social systems are also considered. As a result, the most significant cultural-cum-civilizational systems are distinguished – the West, China, the Islamic world and Russia, which represent four global trends or four vectors of power that fundamentally affect the current state and prospects of world development. It is emphasized that the West and China have a global strategy, provided by objective circumstances. The Islamic world and Russia occupy an important geopolitical position and also have a special status in the global world.
