If you hear Chinglish, Japlish, Konglish or something similar in the radio and both cannot articulate themselves on the radio then you agree that the test is needed. Who testīs the other 4 ICAO languages? Chinese, Russian, Spanish and French???? Fears are within some far east operators that they may cannot "pass" 20% of the present pilots they have into the minimum level required. More Expats to fill the gaps? What a mess, you are not welcome as you "take" a Job of another Buddy....
Fly safe and land happy
