Swiss government buys crude oil nigeria envoy

I think there may be some confusion here.

The Swiss government does not typically buy crude oil from Nigeria or any other country. Switzerland is a landlocked country with no oil reserves of its own, and it relies on imports to meet its energy needs.

However, it's possible that you may be referring to a specific transaction or agreement between a Swiss company and a Nigerian oil company. Could you provide more context or clarify what you mean by "Swiss government buys crude oil Nigeria envoy"?

If you meant to ask about a specific news article or report, I'd be happy to help you fact-check it.
