You’ve made the requirements impossible to satisfy when you added “non-self-serving motivations”. The world is relatively small and disasters have ripple effects. Almost any action a country takes will either help or hurt them. Since the people in charge will mostly try to take actions that help their country, they look self serving now. A sibling comment mentioned the Australian intervention in East Timor. I can easily dismiss that by saying “well the Australians have a vested interest in a stable neighbourhood. They’re just self pricks looking out for themselves”. This statement would be technically correct but also pretty meaningless in this discussion.
