Advice on how to approach my CFO (Nestle)

Hello All,

I am working in Nestle as an expatriate in what one can call a difficult country. I have been performing well and I am being strongly considered as a CFO for a small country for my next step. I have a meeting with the CFO of the whole region soon but here are the issues:

1) My dream is to work in Latin America as a CFO (or country controller as they say in Nestle) however my current market is somewhere else. There is therefore a risk that they want to keep me here

2) I have recently rejected to do a pretty big project and the region CFO took it a bit wrongly even though I had strong justification, at least in my opinion

3) I would be kind of ok to stay in my region as my ultimate goal is to get the CFO position but I would have to wait for the current CFO to leave and it might take a bit longer

Any advice on how to approach him to keep the latin america door open as well as my region door open ?
