Large transport crew was forced to initiate turn to final, while on vectors, at sequ. Turn was initiated to avoid high terrain. Approach control communication was complicated by the use of non standard spanish by the controller.

Narrative:
Accepted vectors for the VOR ILS runway 35 approach (GS OTS). Cleared to 12000 ft and given a heading of approximately 230 degrees. At the qit 165 degree radial and 18 DME, queried controller for a turn onto the localizer. Response from ATC was, standby. He then continued to speak to other aircraft in spanish. At 18.5 DME I turned to join the localizer due to terrain issues. Informed ATC twice of our turn before they responded. Without TCAS we were not sure of the position of other aircraft since spanish was being spoken on the frequency. Controllers in south and central america need to be convinced of the importance of the ICAO standard of english as the international aviation language.

Narrative: ACCEPTED VECTORS FOR THE VOR ILS RWY 35 APCH (GS OTS). CLRED TO 12000 FT AND GIVEN A HEADING OF APPROX 230 DEGS. AT THE QIT 165 DEG RADIAL AND 18 DME, QUERIED CTLR FOR A TURN ONTO THE LOCALIZER. RESPONSE FROM ATC WAS, STANDBY. HE THEN CONTINUED TO SPEAK TO OTHER ACFT IN SPANISH. AT 18.5 DME I TURNED TO JOIN THE LOCALIZER DUE TO TERRAIN ISSUES. INFORMED ATC TWICE OF OUR TURN BEFORE THEY RESPONDED. WITHOUT TCAS WE WERE NOT SURE OF THE POS OF OTHER ACFT SINCE SPANISH WAS BEING SPOKEN ON THE FREQ. CTLRS IN S AND CENTRAL AMERICA NEED TO BE CONVINCED OF THE IMPORTANCE OF THE ICAO STANDARD OF ENGLISH AS THE INTL AVIATION LANGUAGE.
