0 relating to animals that have bilateral symmetry (= two sides of their bodies are a mirror image of each other) --

Our bilaterial aid programme for 1981–82 will be £1·5 million.
It might appear that, in that case, we should withdraw from the agency and concentrate on our national programme and bilaterial projects.
