Un peacekeeping nigeria re elected to united nations committee chair

I think there may be some confusion here.

Nigeria has not been re-elected to the United Nations Committee Chair. In fact, Nigeria has not held a seat on the United Nations Committee Chair in the recent past.

However, Nigeria has been an active member of the United Nations and has contributed to various UN peacekeeping missions around the world. Nigeria has also been a non-permanent member of the United Nations Security Council, serving two terms from 1999 to 2000 and from 2014 to 2015.

It's possible that you may be referring to a different country or organization. Could you provide more context or clarify what you mean by "United Nations Committee Chair"? I'd be happy to help clarify or provide more information if needed!
