China took last place in an aid transparency index of 68 donor nations released on Wednesday, which said the majority of the world's donors were not sharing enough information about their activities.

It took last place for the second year in a row in the index compiled by Publish What You Fund, followed by Greece, Cyprus, Lithuania and Malta, all of which were in the bottom 10 last year.

The United Nations Development Programme topped the index, followed by 2012's top performer, the U.K. Department for International Development, and the U.S. Millennium Challenge Corporation, which held the number one position last year.
