For a country with such low GDP the debt to GDP ratio is not a good indicator of its future. If the country's economy performs at all its GDP could go up multiple times. The situation is different for a middle income country such as Argentina. One can't reasonably expect Argentinian GDP to go up multiple times so the debt is a lot more onerous relative to the GDP. There is a well know "middle income trap" that is hard to escape. The economic upgrade required to move to the developed status from the middle income rung is much harder than what is required to move up from a very low base (really just "normalize") such as Ethiopia.
