Narrative:
Arriving from scl (santiago, chile) via ua 307, scb VOR to bco VOR for ILS landing runway 27L at gru airport (sao paulo, brazil) we received several vectors due traffic. Also we were given descent from FL80 to 6000 ft. Last vector was a northeast heading taking us into MSA FL65. Approximately 300 degree/10 mi from bco VOR experienced a terrain callout on ground proximity warning system (GPWS), executed a pull up to approximately 7000 ft and advised ATC controller (communication was continuous with portuguese due traffic), WX hazy, finally able to communication with controller to advise of our situation and was given final vectors and clearance to land runway 27L with no further incident. I requested operations to meet aircraft at gate. Upon arrival, briefed operations and requested he brief and advise controller. I have enclosed high/low area chart 21-3 to show approximately routing.

Narrative: ARRIVING FROM SCL (SANTIAGO, CHILE) VIA UA 307, SCB VOR TO BCO VOR FOR ILS LNDG RWY 27L AT GRU ARPT (SAO PAULO, BRAZIL) WE RECEIVED SEVERAL VECTORS DUE TFC. ALSO WE WERE GIVEN DSCNT FROM FL80 TO 6000 FT. LAST VECTOR WAS A NE HDG TAKING US INTO MSA FL65. APPROX 300 DEG/10 MI FROM BCO VOR EXPERIENCED A TERRAIN CALLOUT ON GND PROX WARNING SYS (GPWS), EXECUTED A PULL UP TO APPROX 7000 FT AND ADVISED ATC CTLR (COM WAS CONTINUOUS WITH PORTUGUESE DUE TFC), WX HAZY, FINALLY ABLE TO COM WITH CTLR TO ADVISE OF OUR SITUATION AND WAS GIVEN FINAL VECTORS AND CLRNC TO LAND RWY 27L WITH NO FURTHER INCIDENT. I REQUESTED OPS TO MEET ACFT AT GATE. UPON ARR, BRIEFED OPS AND REQUESTED HE BRIEF AND ADVISE CTLR. I HAVE ENCLOSED HIGH/LOW AREA CHART 21-3 TO SHOW APPROX RTING.
