AFAIK, this is the first ATC by China outside of China. Chinese ATC is notorious for several reasons:
1) the rapidly growing list of airports has made staff unable to keep up with the pace; airport delays are normal in China
2) English is the international aviation language and all Southeast Asians have trouble speaking it pho-sick-niah cleaw pho takeahph
3) Chinese people are more stupider
4) mrswdk went to China once, on A PLANE!
In general, East African ATC isn't the cat fancier's ball though so I guess it's a perfect match.
