I think your best bet is just to refer to regions or specific countries. The "developing" part of developing countries creates a false dichotomy. The World Bank doesn't even use it anymore (https://qz.com/685626/the-world-bank-is-eliminating-the-term-developing-country-from-its-data-vocabulary/ https://qz.com/685626/the-world-bank-is-eliminating-the-term...). Just say South East Asia or Sub-Saharan Africa, or whatever you mean.
