Dubi said that Gilbert Felli, the IOC’s long-time executive director, has been assigned to work with Rio after he steps down from his post later this year.
The meetings in Turkey come amid a daily drumbeat of troubles in Brazil. On Monday, striking construction workers and security personnel clashed at Rio’s Olympic Park. Gunshots were fired, but no injuries were reported.
Workers also went on strike on Monday at the Olympic stadium that will be used for track and field at the Games. The venue has been closed since last year to fix problems with its roof.
Guimaraes said the repair work would be completed by December.
The greatest concerns center on the Deodoro complex, an area that is to host venues for eight sports. Work has yet to begin on the site.
In addition, work on the Olympic golf course is far behind schedule, raising concerns for the sport’s return to the games after more than a century.
Guimaraes said grass would begin to be laid on the course later this month and the venue would be ready by September next year.
