I'll give my personal view of it.
It's not necessarily that nations would have ambassadors in specific areas. For ambassadors to other countries, there have been various ambassadors in the past who were appointed for special purposes, and Canada had three previous ones. For other countries, to my knowledge, it's not a normal part to have an ambassador for a specific purpose. There are probably a small number of countries that have significant investments in the fishery, as we would have.
I don't know if there is anything specific.
