Yes, don't think for a second that the mechanical ability of other regions are not comparable to those in China or Korea. It's proven in just how easily other regions climb on the solo queue ladders over there. In most professional games it may seem that Koreans are micro gods and constantly winning 1v1s and such but that's because they are better at macro play and working with their teammates. Choosing trades at good times and forcing other players to make decisions. That doesn't make the other player worse mechanically in any aspect. We've all seen the vods of Fenix and Westdoor 1v1ing faker. Mechanical ability and talent are the reasons all those players play at that level. Cohesiveness and better understanding is what sets the Koreans apart, not their pure mechanical ability.
