The World Health Organization has announced that it will be approving the new target of cutting down premature deaths caused by chronic illnesses, such as cardiovascular diseases, by more than 25 percent by 2025.
Cardiovascular disease, diabetes, cancer and chronic respiratory conditions are known in medical terms as non-communicable diseases (NCDs) and represent the world's biggest killers -- accounting for 63 percent of all deaths.
About a quarter of victims die prematurely, between the ages of 30 and 70.
Late Thursday, WHO member states meeting in Geneva made a "landmark" decision to fix the 25 percent reduction target which is expected to be formally adopted on Saturday, the UN health agency said.
It was agreed along with a raft of measures to address the prevention and control of NCDs, which have rocketed in developing countries in recent years.
About 80 percent of premature deaths from NCDs now occur in low and middle-income countries.
"The focus of attention of the world community on the largest killer is now on course," said Douglas Bettcher from the WHO's chronic diseases unit.
"The architecture to support developing countries in addressing NCDs and their risk factors is now in place."
NCDs also constitute a massive financial burden. A recent Harvard study found that left unattended they could result in lost productivity in low and middle income countries worth $7 trillion up to 2025.
"This is something that would, in an era of globalisation and ongoing financial crisis, have major effects for the entire world," said Bettcher.
In the resolution adopted by WHO member states but yet to be formally approved, countries also backed further work aimed at producing targets on NCD risk factors, namely tobacco use, alcohol abuse, unhealthy diet and physical inactivity.
They called for a formal meeting to be held before the end of October to conclude work on a "global monitoring framework" to prevent and control NCDs.
