Narrative:

Aircraft reported 3 mile left base; as instructed; and was then instructed to widen out to the west to follow a cirrus on 6 mile final. The pilot mumbled something unintelligible and when questioned as to whether or not he got the instruction again reported on the base. Was again told to widen out to the west to follow traffic. To which he replied that he was on base. I advised that I knew he was on base and I wanted him to widen out as previously instructed. He replied that he was on base as instructed. I then had to tell him to turn right immediately; to avoid imminent conflict with the traffic on final. Once again; no communication with a foreign student pilot due to the fact that he has no idea what I'm telling him. This would be comical if it wasn't for the fact that this was the third such incident in 24 minutes and I was frustrated. I don't understand how this can possibly be acceptable; or safe; because this is a 'training environment'. I'm not buying it.
