Anti-corruption activists gather in Doha

Hundreds of envoys from around the world are in Qatar's capital Doha, seeking to expand the powers of a UN accord to battle financial corruption.

The five-day gathering begins Monday. Officials from the United Nations and World Bank are expected to call on the international community to help track down and return looted money.

The meeting also will try to establish an independent review process to look into countries' books and try to detect missing funds.

But some nations such as China and Russia are resisting those measures. Two previous meetings in the past years have failed to break the impasse.

UN reports estimate up to $1.6 trillion in siphoned public funds crosses borders each year.
