Name the cities hosting major international sporting events including the Olympics, Universiade, IAAF World Championships in Athletics and FINA World Aquatics Championships since year 2000

Yeah I thought about it but here I want to highlight how these events are all concentrated in the same region, like three consecutive Olympics in northeast Asia.
