In 1970, the world’s rich countries agreed to give 0.7% of their gross national income as official international development aid, annually.
Since that time, billions have certainly been given each year, but rarely have the rich nations actually met their promised target.For example, the US is often the largest donor in dollar terms, but ranks amongst the lowest in terms of meeting the stated 0.7% target.
Furthermore, aid has often come with a price of its own for the developing nations. Common criticisms, for many years, of foreign aid, have included the following:
Aid is often wasted on conditions that the recipient must use overpriced goods and services from donor countries
Most aid does not actually go to the poorest who would need it the most
Aid amounts are dwarfed by rich country protectionism that denies market access for poor country products
now every country is growing up , and there lot of countries helping other countries also , but it depends on the country how they co -operate with each other, if one country helps in economy ,the other country something in another way , that's how relationship between country works, it is not poor or rich.
