KABUL - Afghanistan, North Korea and Somalia have been viewed as the world's most corrupt countries in a survey released by graft watchdog Transparency International (TI) on Tuesday.
Worldwide, almost 70 percent of nations are thought to have a "serious problem" with public servants on the take, and none of the 177 countries surveyed this year got a perfect score, said the Berlin-based non-profit group.
Transparency International's annual list is the most widely used indicator of sleaze in political parties, police, justice systems and civil services, undermining development and the fight against poverty.
"Corruption hurts the poor most," lead researcher Finn Heinrich said. About Afghanistan, Heinrich called the nation's story "a sobering".
He said they had not seen tangible improvements in Afghanistan, where most NATO-led Western forces are pulling out next year.
Also at the bottom of the list is North Korea, "an absolutely closed totalitarian society", said Heinrich, where defectors report that famine is worsening corruption "because you have to know someone in the party who is corrupt in order to even survive".
Among the "most improved" countries, although from a low base, was Myanmar, facing an investment boom, has formally committed to transparency and accountability rules.
"That's the only way countries can avoid the 'resource curse', where the resources are only available to a very small elite," said Heinrich. "Nigeria and other oil-rich countries are obviously very good examples."
Huguette Labelle, chair of Transparency, said "all countries still face the threat of corruption at all levels of government, from the issuing of local permits to the enforcement of laws and regulations".
The group says that because corruption is illegal and secretive, it cannot be meaningfully measured.
Instead Transparency collates expert views on the problem from bodies such as the World Bank, African Development Bank, Economist Intelligence Unit, Bertelsmann Foundation, Freedom House and other groups.
It then ranks countries on a scale of 0-100, where 0 means a country's public sector is considered highly corrupt and 100 means its is regarded as very clean.
The latest survey "paints a worrying picture", said Transparency. "While a handful perform well, not one single country gets a perfect score. More than two-thirds score less than 50."
The bottom-ranked countries, scoring 10 to 19, included Iraq, Syria, Libya, Sudan and South Sudan, Chad, Equatorial Guinea, Guinea-Bissau, Haiti, Turkmenistan, Uzbekistan and Yemen.
At the top, between 80 and 89, aside from Denmark and New Zealand, were Luxembourg, Canada, Australia, the Netherlands, Switzerland, Singapore, Norway, Sweden and Finland.
"The top performers clearly reveal how transparency supports accountability and can stop corruption," said Labelle.
"Still, the better performers face issues like state capture, campaign finance and the oversight of big public contracts which remain major corruption risks."
India ranked 94 on the index, above Pakistan at rank 127 but below China which took the 80th position.
Among countries that have slipped the most on the group's 2013 Corruption Perceptions Index are war-torn Syria as well as Libya and Mali, which have also faced major military conflict in recent years."Corruption is very much linked to countries that fall apart, as you see in Libya, Syria, two of the countries that deteriorated the most," said Heinrich.
"If you look at the bottom of the list, we also have Somalia there. These are not countries where the government is functioning effectively, and people have to take all means in order to get by, to get services, to get food, to survive." (Pajhwok)
