The world is moving through "a very important recalibration" of the global geo-economic and geopolitical system, as new actors are rising, said Anton Fedyashin, associate professor at American University, in an interview with CGTN's "Facts Tell". The American historian shared his views on the "hegemonic decline" of the United States and why it should approach it in an "unemotional fashion," in comparison with the way the British Empire adjusted to its role back in the 1940s and 1950s.
