Each economically advanced country will progressively increase its official development assistance to the developing countries and will exert its best efforts to reach a minimum net amount of 0.7% of its gross national product at market prices. In 2013, the UK Government aims to achieve the target of contributing 0.7% of its national income in aid.
0.7% of donor GNI
0.71% of donor GNI in 2014
No gap-- 0.01% of GNI above target
At subsequent UN and other international conferences and summits many developed countries reaffirmed the target and extended the deadline to 2015.
