Denmark and New Zealand performed best with scores of 91. Afghanistan, North Korea and Somalia tied last with 8 points each.

The change reflects the benefits of introducing more open and democratic rules after years of military rule, according to Transparency International's Asia Pacific Director, Srirak Plipat.

Myanmar also ratified an international treaty against corruption in December 2012 and the parliament approved an anti-corruption law in July, although this is yet to come into force.

While Greece's score rose four points this year to 40, but remained the lowest ranking country in the European Union in 80th place. Brunei, Laos, Senegal, Nepal, Estonia, Lesotho and Latvia also improved.

The UK jumped from 17th to 14th place with a score of 76, two points up from last year. The U.S. did not change from last year, ranking 19th with a score of 73. China's rank did not change. Australia dropped two places to 9th position with a score of 81.

The Corruption Perceptions Index is based on perceptions of corruption in public institutions like political parties, police and justice systems according to experts and business people.

Strong access to information systems and rules governing the behavior of public officials can help a country improve, while a lack of accountability and weak public institutions damages these perceptions, Transparency International said.

The organization called on public institutions and officials to be more open, adding that corruption remains notoriously difficult to investigate and prosecute.
