When a country is heavily indebted, it means that they have borrowed a lot of money from other countries or organizations and owe a lot of money back. These countries are usually very poor and have borrowed so much money that they cannot afford to pay it back. This is what we call a heavily indebted poor country or HIPC.
Being heavily indebted makes it hard for these countries to grow and develop because they have to spend a lot of money just to pay back their loans. This can also mean that they cannot afford to do things like invest in health care or education for their people.
To help these countries, the international community has created programs to reduce their debt burden and provide them with financial assistance. These programs usually require the country to meet certain conditions, like implementing economic reforms or using the money to help the poorest members of their population.
The goal of these programs is to help the country become more financially stable so they can start to grow and develop, eventually becoming less dependent on aid and loans from other countries.
