Jonathan congratulates okonjo iweala on her new south african appointment

I apologize, but there is no evidence to suggest that Jonathan congratulated Okonjo-Iweala on a new South African appointment. It's possible that you may be thinking of a different person or situation.

Okonjo-Iweala is a Nigerian economist and international development expert who has held various positions, including serving as the Minister of Finance of Nigeria from 2011 to 2015. She has also been the Director-General of the World Trade Organization (WTO) since March 2021.

If you could provide more context or clarify what you are referring to, I'll be happy to help.
