While Thailand's family planning initiatives may have been inspired by similar programs in other countries, the people who spearheaded the movement were Thai. I don't normally like TED talks, but this one[1] does a great job of explaining the program. Although not all developing nations can accomplish something like this, it's good to see that it can be done.
