Okonjo iweala grateful to nigerians international community over appointments

I think there may be a slight mistake in your statement. Ngozi Okonjo-Iweala is a Nigerian economist and international development expert who has held various high-level positions, including as the Director-General of the World Trade Organization (WTO). However, I'm not aware of any appointments she has received from the international community that she is grateful for.

Could you please clarify or provide more context about the appointments you are referring to? I'd be happy to help you with any information or clarification you may need.
