Narrative:

A lifeguard aircraft was en route from ZZZZ. ZZZ1 approach manually passed the flight plan to me that was ZZZZ2-ZZZ.....at 10000. Aircraft checked on twenty south of ZZZ1 requesting direct to destination. I told him I needed him to stay on the flight plan route. Aircraft informed me that they were minimum fuel. I called ZZZ1 who coordinates ZZZZ2 airspace since we don't have a direct line to ZZZZ2 approach even though airspace is directly adjacent to us. ZZZ1 told me that he is in uncontrolled airspace and they cannot give me control for the aircraft. I called the lifeguard aircraft and told him ZZZ1 approach told me unable and if the only way they could go to the airport would be to declare emergency fuel. Aircraft declared emergency fuel at which point I cleared them direct to his destination. Coordinated with aircraft destination approach and aircraft landed safely. There was no way to prevent occurrence without redesign of the foreign country's airspace. Ability for direct coordination with ZZZZ2 would have been very helpful. Tone of pilot's voice sounded like they very much needed direct the airport and the only way I could do that would be emergency fuel; not minimum fuel. That's why I gave the pilot that option and he declared emergency fuel.
