A report has found there has been significant progress towards tackling the problem of child labour, especially in Asia.
Research by the International Labour Organisation (ILO) shows the number of working children has dropped globally by a third since 2000.
The ILO's child labour specialist in Bangkok, Simrin Singh, has told Asia Pacific the decline is the result of hard work by international policy makers.
"I think a lot of effort has been put by the United Nations states and various actors in making the issue of child labor visible and taking policy actions to try to end it," she said.
Ms Singh says a lot of investment has been made in education on the issue and tackling poverty.
She says there has also been considerable economic growth in a number of Asian nations.
"Many countries in Asia are developing; moving from least developed countries status to middle income countries."
Ms Singh says in the past 13 years the number of children in the Asia Pacific region has reached 78 million, down from 113 million.
She says despite this, more still needs to be done towards reaching a United Nations target of eliminating the worst forms of child labour by 2016.
Ms Singh says there has been a shift in the type of industries engaging child labour, with many now working in the service sector instead of agriculture.
The ILO is urging Australia and New Zealand to sign up to the convention to end the worst forms of child labour within the next three years, as they are among only a handful of countries yet to do so.
It says such a move would provide much-needed political momentum.
