Under what conditions can two or three socio-economic units merge?
A. They can merge if there is economic parity, cultural mixing, communication facilities and administrative efficiency. Merging will benefit the people. It is preferable for small units or states to merge into larger units. As the units reach higher levels of development, this unification process will gradually lead to one socio-economic unit for the entire country. As this process continues, entire regions such as Southeast Asia or South and Southeast Asia both will combine to form one socio-economic unit.
