Foreign speaking flight crew failed to follow approach control clearance by turning base leg before being instructed to do so resulting in ATC intervention and instructions to turn away from traffic on final approach. Controller reporter believed that the mistake by the flight crew was caused by the crew's unfamiliarity with the english language.

Narrative:
Air carrier X was heading 070 degrees from smo VOR, descending to 2500 ft, expecting ILS runway 24R. I advised air carrier X to 'change ILS to ILS runway 24L, localizer frequency is 111.7.' pilot mumbled something unintelligible. Next thing I saw was air carrier X turning sbound toward the final approach courses. I instructed the aircraft to turn right heading 360 degrees, away from aircraft on final. Standard IFR separation was not maintained. This is another example of foreign air carrier pilots doing the unexpected and compromising safety by their actions. My recommendation is to not give other than simple, standard instructions to foreign pilots. This pilot obviously did not have an understanding of the english language.

Title: FOREIGN SPEAKING FLC FAILED TO FOLLOW APCH CTL CLRNC BY TURNING BASE LEG BEFORE BEING INSTRUCTED TO DO SO RESULTING IN ATC INTERVENTION AND INSTRUCTIONS TO TURN AWAY FROM TFC ON FINAL APCH. CTLR RPTR BELIEVED THAT THE MISTAKE BY THE FLC WAS CAUSED BY THE CREW'S UNFAMILIARITY WITH THE ENGLISH LANGUAGE.
Narrative: ACR X WAS HDG 070 DEGS FROM SMO VOR, DSNDING TO 2500 FT, EXPECTING ILS RWY 24R. I ADVISED ACR X TO 'CHANGE ILS TO ILS RWY 24L, LOC FREQ IS 111.7.' PLT MUMBLED SOMETHING UNINTELLIGIBLE. NEXT THING I SAW WAS ACR X TURNING SBOUND TOWARD THE FINAL APCH COURSES. I INSTRUCTED THE ACFT TO TURN R HDG 360 DEGS, AWAY FROM ACFT ON FINAL. STANDARD IFR SEPARATION WAS NOT MAINTAINED. THIS IS ANOTHER EXAMPLE OF FOREIGN ACR PLTS DOING THE UNEXPECTED AND COMPROMISING SAFETY BY THEIR ACTIONS. MY RECOMMENDATION IS TO NOT GIVE OTHER THAN SIMPLE, STANDARD INSTRUCTIONS TO FOREIGN PLTS. THIS PLT OBVIOUSLY DID NOT HAVE AN UNDERSTANDING OF THE ENGLISH LANGUAGE.
