Air carrier flight crew reports encountering a tethered balloon at 10;000 feet over cgo on the cgo 1...

Narrative:

During climbout from sbgr (sao paulo) on the cgo 1 (congonhas one departure) scb transition; the captain; first officer; and relief pilot observed a large rectangular balloon; or kite approximately 100 feet in size directly in our flight path at exactly 10;000 feet. The object had a thick line or cable attached to it and descended downward from the object as far as the eye could see. The location of the object was directly in our path located over the congonhas VOR on the departure. While executing the turn on the SID over cgo; all pilots saw the object and I proceeded to take evasive action to prevent hitting the object. The aircraft missed the object by approximately 200 feet. Captain reported the objects location and altitude to departure control. The sbgr ATIS did have warnings of possible balloon activity in the airport area. But; one never expects to see it at 10;000 feet with a large cable attached to it. Please notify the brazilian government on the seriousness of allowing this type of activity to continue. They make announcements on the ATIS; and know they are there; but seem to do little to correct this problem.
